## **Description** 

The 6A Digital PicoDLynx[TM ] power modules are non-isolated dc-dc converters that deliver up to 6A of output current. These modules operate over a wide range of input voltage (VIN = 3Vdc-14.4Vdc) and provide a precisely regulated output voltage from 0.45Vdc to 5.5Vdc, programmable via an external resistor and further adjustable through PMBus. Features include a digital interface using the PMBus protocol, remote On/Off, adjustable output voltage, over current and over temperature protection. The PMBus interface supports a range of commands to control and monitor the module. The Tunable Loop[TM] feature allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area. 

## **Applications** 

- Distributed power architectures 

- Intermediate bus voltage applications 

- Telecommunications equipment 

- Servers and storage applications 

- Networking equipment 

- Industrial equipment

## **Technical Specifications** (continued) 

## **Design Considerations** 

## **Input Filtering** 

The 6A Digital PicoDLynx[TM] module should be connected to a low ac-impedance source. A highly inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability. 

To minimize input voltage ripple, ceramic capacitors are recommended at the input of the module. Figure 37 shows the input ripple voltage for various output voltages at 6A of load current with 1x22 µF or 2x22 µF ceramic capacitors and an input of 12V.

**Figure 37. Input ripple voltage for various output voltages with 1x22 µF or 2x22 µF ceramic capacitors at the input (6A load). Input voltage is 12V.** 

## **Output Filtering** 

These modules are designed for low output ripple voltage and will meet the maximum output ripple specification with 0.1 µF ceramic and 22 µF ceramic capacitors at the output of the module. However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. 

output capacitance as specified in the electrical specification table. Optimal performance of the module can be achieved by using the Tunable Loop[TM] feature described later in this data sheet.

**Figure 38.  Output ripple voltage for various output voltages with external 1x22 µF, 1x47 µF, or 2x47 µF ceramic capacitors at the output (6A load). Input voltage is 12V.** 

## **Safety Considerations** 

For safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL ANSI/UL* 62368-1 and CAN/CSA[+] C22.2 No. 62368-1 Recognized, DIN VDE 0868-1/A11:2017 (EN62368-1:2014/A11:2017) 

For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV) or ES1, the input must meet SELV/ES1 requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. 

The input to these units is to be provided with a fast acting fuse with a maximum rating of 10A in the positive input lead. An example of such a fuse is the 318 series from Little fuse. 

To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figure 38 provides output ripple information for different external capacitance values at various Vo and a full load current of 6A. For stable operation of the module, limit the capacitance to less than the maximum

## **Technical Specifications** (continued) 

## **Analog Feature Descriptions** 

## **Remote On/Off** 

The module can be turned ON and OFF either by using the ON/OFF pin (Analog interface) or through the PMBus interface (Digital). The module can be configured in a number of ways through the PMBus interface to react to the two ON/OFF inputs: 

turned ON pulling the On/Off pin low, turning transistor Q1 OFF resulting in the PWM Enable pin going high. 

## **Digital On/Off** 

Please see the Digital Feature Descriptions section 

- Module ON/OFF can be controlled only through the analog interface (digital interface ON/OFF commands are ignored) 

- Module ON/OFF can be controlled only through the PMBus interface (analog interface is ignored) 

- Module ON/OFF can be controlled by either the analog or digital interface 

The default state of the module (as shipped from the factory) is to be controlled by the analog interface only. If the digital interface is to be enabled, or the module is to be controlled only through the digital interface, this change must be made through the PMBus. These changes can be made and written to non-volatile memory on the module so that it is remembered for subsequent use. 

**Figure 39. Circuit configuration for using positive On/Off logic.** 

## **Analog On/Off** 

The 6A Digital PicoDLynx[TM] power modules feature an On/Off pin for remote On/Off operation. Two On/Off logic options are available. In the Positive Logic On/Off option, (device code suffix “4” – see Ordering Information), the module turns ON during a logic High on the On/Off pin and turns OFF during a logic Low. With the Negative Logic On/Off option, (no device code suffix, see Ordering Information), the module turns OFF during logic High and ON during logic Low. The On/Off signal should be always referenced to ground. For either On/Off logic option, leaving the On/ Off pin disconnected will turn the module ON when input voltage is present. 

For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 39. When the external transistor Q2 is in the OFF state, the internal transistor Q1 is turned ON, and the internal PWM #Enable signal is pulled low causing the module to be ON. When transistor Q2 is turned ON, the On/Off pin is pulled low and the module is OFF. A suggested value for Rpullup is 20k Ω . 

**Figure 40. Circuit configuration for using negative On/Off logic.** 

## **Monotonic Start-up and Shutdown** 

The module has monotonic start-up and shutdown behavior for any combination of rated input voltage, output current and operating temperature range. 

Startup into Pre-biased Output 

The module can start into a prebiased output as long as the prebias voltage is 0.5V less than the set output voltage. 

For negative logic On/Off modules, the circuit configuration is shown in Fig. 40. The On/Off pin should be pulled high with an external pull-up resistor (suggested value for the 3V to 14V input range is 20Kohms). When transistor Q2 is in the OFF state, the On/Off pin is pulled high, transistor Q1 is turned ON and the module is OFF. To turn the module ON, Q2 is Page 14

## **Analog Output Voltage Programming** 

The output voltage of the module is programmable to any voltage from 0.6dc to 5.5Vdc by connecting a resistor between the Trim and SIG_GND pins of the module. Certain restrictions apply on the output voltage set point depending on the input voltage. These are shown in the Output Voltage vs. Input Voltage Set Point Area plot in Fig. 41.  The Upper Limit curve shows that for output voltages lower than 1V, the input voltage must be lower than the maximum of 14.4V. The Lower Limit curve shows that for output voltages higher than 0.6V, the input voltage needs to be larger than the minimum of 3V.

## **Digital Output Voltage Adjustment** 

Please see the Digital Feature Descriptions section. 

## **Remote Sense** 

The power module has a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage between the sense pins (VS+ and VS-). The voltage drop between the sense pins and the VOUT and GND pins of the module should not exceed 0.5V. 

## **Analog Voltage Margining** 

**Figure 42. Circuit configuration for programming output voltage using an external resistor.** 

**Caution** – Do not connect SIG_GND to GND elsewhere in the layout 

Output voltage margining can be implemented in the module by connecting a resistor, Rmargin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to output pin for margining-down.  Figure 43 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at **omnionpower.com** under the Downloads section, also calculates the values of Rmargin-up and Rmargin-down for a specific output voltage and % margin. Please consult your local OmniOn Critical Power technical representative for additional details. 

Without an external resistor between Trim and SIG_GND pins, the output of the module will be 0.6Vdc.To calculate the value of the trim resistor, Rtrim for a desired output voltage, should be as per the following equation:

## **Digital Output Voltage Margining** 

Please see the Digital Feature Descriptions section. 

## **Output Voltage Sequencing** 

The power module includes a sequencing feature, EZ-SEQUENCE that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When not using the sequencing feature, leave it unconnected. 

The voltage applied to the SEQ pin should be scaled down by the same ratio as used to scale the output voltage down to the reference voltage of the module. This is accomplished by an external resistive divider connected across the sequencing voltage before it is fed to the SEQ pin as shown in Fig. 44. In addition, a small capacitor (suggested value 100pF) should be connected across the lower resistor R1. 

For all DLynx modules, the minimum recommended delay between the ON/OFF signal and the sequencing signal is 10ms to ensure that the module output is ramped up according to the sequencing signal. This ensures that the module soft-start routine is completed before the sequencing signal is allowed to ramp up. 

When the scaled down sequencing voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches the set-point voltage. The final value of the sequencing voltage must be set higher than the set-point voltage of the module. The output voltage follows the sequencing voltage on a one-to-one basis. By connecting multiple modules together, multiple modules can track their output voltages to the voltage applied on the SEQ pin. 

The module’s output can track the SEQ pin signal with slopes of up to 0.5V/msec during power-up or powerdown. 

To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltage of the modules tracks the voltages below their set- point voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential. 

Note that in all digital DLynx series of modules, the PMBus Output Undervoltage Fault will be tripped when sequencing is employed. This will be detected using the STATUS_WORD and STATUS_VOUT PMBus commands. In addition, the SMBALERT# signal will be asserted low as occurs for all faults 

## **Overcurrent Protection** 

To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. 

## **Digital Adjustable overcurrent Warning** 

Please see the Digital Feature Descriptions section.

Rev. 1.8 

## **Technical Specifications** (continued) 

## **Overtemperature Protection** 

To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shut down if the overtemperature threshold of 150[o] C(typ) is exceeded at the thermal reference point Tref. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. 

## **Digital Temperature Status via PMBus** 

Please see the Digital Feature Descriptions  section. 

## **Digitally Adjustable Output Over and Under Voltage Protection** 

Please see the Digital Feature Descriptions section. 

## **Measuring Output Current, Output Voltage and Input Voltage** 

Please see the Digital Feature Descriptions section. 

## **Dual Layout** 

Identical dimensions and pin layout of Analog and Digital PicoDLynx modules permit migration from one to the other without needing to change the layout. To support this, 2 separate Trim Resistor locations have to be provided in the layout. As shown in Fig. 46, for the digital modules, the resistor is connected between the TRIM pad and SGND and in the case of the analog module it is connected between TRIM and GND. 

## **Input Undervoltage Lockout** 

At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. Digitally Adjustable Input Undervoltage Lockout Please see the Digital Feature Descriptions section. 

## **Digitally Adjustable Power Good Thresholds** 

Please see the Digital Feature Descriptions section. 

## **Synchronization** 

The module switching frequency can be synchronized to a signal with an external frequency within a specified range. Synchronization can be done by using the external signal applied to the SYNC pin of the module as shown in Fig. 45, with the converter being synchronized by the rising edge of the external signal. The Electrical Specifications table specifies the requirements of the external SYNC signal. If the SYNC pin is not used, the module should free run at the default switching frequency. **If synchronization is not being used, connect the SYNC pin to GND.** 

**Figure 45. External source connections to synchronize switching frequency of the module.** 

**Figure 46. Connections to support either Analog or Digital PicoDLynx on the same layout.** 

**Caution** – For digital modules, do not connect SIG_GND to GND elsewhere in the layout 

## **Tunable Loop[TM]** 

The module has a feature that optimizes transient response of the module called Tunable Loop[TM] . 

External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise (see Figure 38) and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes. Adding external capacitance however affects the voltage control loop of the module, typically causing the loop to slow down with sluggish response. Larger values of external capacitance could also cause the module to become unstable. 

The Tunable Loop[TM] allows the user to externally adjust the voltage control loop to match the filter network connected to the output of the module. The Tunable Loop[TM] is implemented by connecting a series R-C between the VS+ and TRIM pins of the module, as shown in Fig. 47. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module.

Note: The capacitors used in the Tunable Loop tables are 47 μ F/3 mΩ ESR ceramic and 330 μ F/12 mΩ ESR polymer capacitors. 

## **Digital Feature Descriptions** 

**Figure. 47. Circuit diagram showing connection of RTUNE and CTUNE to tune the control loop of the module.** 

Recommended values of RTUNE and CTUNE for different output capacitor combinations are given in Table 2. Table 2 shows the recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 1000uF that might be needed for an application to meet output ripple and noise requirements. Selecting RTUNE and CTUNE according to Table 2 will ensure stable operation of the module. In applications with tight output voltage limits in the presence of dynamic current loading, additional output capacitance will be required. Table 3 lists 

recommended values of RTUNE and CTUNE in order to meet 2% output voltage deviation limits for some common output voltages in the presence of a 3A to 6A step change (50% of full load), with an input voltage of 12V. 

Please contact your OmniOn technical representative to obtain more details of this feature as well as for guidelines on how to select the right value of external R-C to tune the module for best transient performance and stable operation for other output capacitance values

## **PMBus Interface Capability** 

The 6A Digital PicoDLynx[TM] power modules have a PMBus interface that supports both communication and control. The PMBus Power Management Protocol Specification can be obtained from www.pmbus.org. The modules support a subset of version 1.1 of the specification (see Table 6 for a list of the specific commands supported). Most module parameters can be programmed using PMBus and stored as defaults for later use. 

All communication over the module PMBus interface must support the Packet Error Checking (PEC) scheme. The PMBus master must generate the correct PEC byte for all transactions, and check the PEC byte returned by the module. 

The module also supports the SMBALERT# response protocol whereby the module can alert the bus master if it wants to talk. For more information on the SMBus alert response protocol, see the System Management Bus (SMBus) specification. 

The module has non-volatile memory that is used to store configuration settings. Not all settings programmed into the device are automatically saved into this non-volatile memory, only those specifically identified as capable of being stored can be saved (see Table 6 for which command parameters can be saved to non-volatile storage). 

## **PMBus Data Format** 

For commands that set thresholds, voltages or report such quantities, the module supports the “Linear” data format among the three data formats supported by PMBus. The Linear Data Format is a two byte value with an 11-bit, two’s complement mantissa and a 5-bit, two’s complement exponent. The format of the two data bytes is shown below:

## **Technical Specifications** (continued) 

## **PMBus Data Format (continued)** 

The value is of the number is then given by 

Value = Mantissa x 2[Exponent] 

## **PMBus Addressing** 

The power module can be addressed through the PMBus using a device address. The module has 64 possible addresses (0 to 63 in decimal) which can be set using resistors connected from the ADDR0 and ADDR1 pins to SIG_GND. Note that some of these addresses (0, 1, 2, 3, 4, 5, 6, 7, 8, 12, 40 in decimal) are reserved according to the SMBus specifications and may not be useable. The address is set in the form of two octal (0 to 7) digits, with each pin setting one digit. The ADDR1 pin sets the high order digit and ADDR0 sets the low order digit. The resistor values suggested for each digit are shown in Table 4 (1% tolerance resistors are recommended). Note that if either address resistor value is outside the range specified in Table 4, the module will respond to address 127

**Table 4** 

The user must know which I[2] C addresses are reserved in a system for special functions and set the address of the module to avoid interfering with other system operations. Both 100kHz and 400kHz bus speeds are supported by the module. Connection for the PMBus interface should follow the High Power DC specifications given in section 3.1.3 in the SMBus specification V2.0 for the 400kHz bus speed or the Low Power DC specifications in section 3.1.2. The complete SMBus specification is available from the SMBus web site, SMBus.org 

**Figure 48. Circuit showing connection of resistors used to set the PMBus address of the module.** 

## **PMBus Enabled On/Off** 

The module can also be turned on and off via the PMBus interface. The OPERATION command is used to actually turn the module on and off via the PMBus, while the ON_OFF_CONFIG command configures the combination of analog ON/OFF pin input and PMBus commands needed to turn the module on and off. Bit [7] in the OPERATION command data byte enables the module, with the following functions: 

## 0 : Output is disabled 

## 1 : Output is enabled 

This module uses the lower five bits of the ON_OFF_CONFIG data byte to set various ON/OFF options as follows: 

|**Bit Position**|**4**|**3**|**2**|**1**|**0**|
|---|---|---|---|---|---|
|Access|r/w|r/w|r/w|r/w|r|
|Function|PU|CMD|CPR|POL|CPA|
|Default Value|1|0|1|1|1|



PU: Sets the default to either operate any time input power is present or for the ON/OFF to be controlled by the analog ON/OFF input and the PMBus OPERATION command. This bit is used together with the CP, CMD and ON bits to determine startup. 

|**Bit Value**|**Action**|
|---|---|
|0|Module powers up any time power is<br>present regardless of state of the analog<br>ON/OFFpin|
|1|Module does not power up until<br>commanded by the analog ON/OFF pin<br>and the OPERATION command as<br>programmed in bits [2:0] of the<br>ON_OFF_CONFIG register.|



CMD: The CMD bit controls how the device responds to the OPERATION command.

## **PMBus Adjustable Soft Start Rise Time** 

The soft start rise time can be adjusted in the module via PMBus. When setting this parameter, make sure that the charging current for output capacitors can be delivered by the module in addition to any load current to avoid nuisance tripping of the overcurrent protection circuitry during startup. The TON_RISE command sets the rise time in ms, and allows choosing soft start times between 600 μ s and 9ms, with possible values listed in Table 5. Note that the exponent is fixed at -4 (decimal) and the upper two bits of the mantissa are also fixed at 0.

**Table 5** 

## **Output Voltage Adjustment Using the PMBus** 

The VOUT_SCALE_LOOP parameter is important for a number of PMBus commands related to output voltage trimming, margining, over/under voltage protection and the PGOOD thresholds. The output voltage of the module is set as the combination of the voltage divider formed by RTrim and a 20kΩ upper divider resistor inside the module, and the internal reference voltage of the module. The reference 

voltage VREF is nominally set at 600mV, and the output regulation voltage is then given by 

**==> picture [140 x 36] intentionally omitted <==**

Hence the module output voltage is dependent on the value of RTrim which is connected external to the module. The information on the output voltage divider ratio is conveyed to the module through the VOUT_SCALE_LOOP parameter which is calculated as follows: 

**==> picture [208 x 36] intentionally omitted <==**

The VOUT_SCALE_LOOP parameter is specified using the “Linear” format and two bytes. The upper five bits [7:3] of the high byte are used to set the exponent which is fixed at –9 (decimal). The remaining three bits of the high byte [2:0] and the eight bits of the lower byte are used for the mantissa. The default value of the mantissa is 00100000000 corresponding to 256 (decimal), corresponding to a divider ratio of 0.5. The maximum value of the mantissa is 512 corresponding to a divider ratio of 1. Note that the resolution of the VOUT_SCALE_LOOP command is 0.2%. 

When PMBus commands are used to trim or margin the output voltage, the value of VREF is what is changed inside the module, which in turn changes the regulated output voltage of the module. 

The nominal output voltage of the module can be adjusted with a minimum step size of 0.4% over a ±25% range from nominal using the VOUT_TRIM command over the PMBus. 

The VOUT_TRIM command is used to apply a fixed offset voltage to the output voltage command value using the “Linear” mode with the exponent fixed at –10 (decimal). The value of the offset voltage is given by 

**==> picture [148 x 10] intentionally omitted <==**

This offset voltage is added to the voltage set through the divider ratio and nominal VREF to produce the trimmed output voltage. The valid range in two’s complement for this command is  –4000h to 3FFFh. The high order two bits of the high byte must both be either 0 or 1.

## **Technical Specifications** (continued) 

upper six bits of the mantissa are fixed at 0 while the lower five bits are programmable. For production codes after April 2013, the value for 

## **Output Voltage Adjustment Using the PMBus (continued)** 

If a value outside of the +/-25% adjustment range is given with this command, the module will set it’s output voltage to the nominal value (as if VOUT_TRIM had been set to 0), assert SMBALRT#, set the CML bit in STATUS_BYTE and the invalid data bit in STATUS_CML. 

IOUT_OC_WARN_LIMIT will be fixed at 8.5A. For earlier production codes the actual value for 

IOUT_OC_WARN_LIMIT will vary from module to module due to calibration during production testing. The resolution of this warning limit is 500mA. The value of the IOUT_OC_WARN_LIMIT can be stored to non-volatile memory using the STORE_DEFAULT_ALL command. 

## **Output Voltage Margining Using the PMBus** 

The module can also have its output voltage margined via PMBus commands. The command 

## **Temperature Status via PMBus** 

VOUT_MARGIN_HIGH sets the margin high voltage, while the command VOUT_MARGIN_LOW sets the margin low voltage. Both the VOUT_MARGIN_HIGH and VOUT_MARGIN_LOW commands use the “Linear” mode with the exponent fixed at –10 (decimal). Two bytes are used for the mantissa with the upper bit [7] of the high byte fixed at 0. The actual margined output voltage is a combination of the VOUT_MARGIN_HIGH or VOUT_MARGIN_LOW and the VOUT_TRIM values as shown below. 

The module can provide information related to temperature of the module through the STATUS_TEMPERATURE command. The command returns information about whether the pre-set over temperature fault threshold and/or the warning threshold have been exceeded. 

## **PMBus Adjustable Output Over and Under Voltage Protection** 

The module has output over and under voltage protection capability. The PMBus command 

VOUT(MH) = (VOUT_MARGIN_HIGH+ VOUT_TRIM) X 2[-10                ] 

VOUT_OV_FAULT_LIMIT is used to set the output over voltage threshold from four possible values: 108%, 110%, 112% or 115% of the commanded output voltage. The command VOUT_UV_FAULT_LIMIT sets the threshold that causes an output under voltage fault and can also be selected from four possible values: 92%, 90%, 88% or 85%. The default values are 112% and 88% of commanded output voltage. Both commands use two data bytes formatted as two’s complement binary integers. The “Linear” mode is used with the exponent fixed to –10 (decimal) and the effective over or under voltage trip points given by: 

VOUT(ML) = (VOUT_MARGIN_LOW+ VOUT_TRIM) X 2[-10                ] 

Note that the sum of the margin and trim voltages cannot be outside the ±25% window around the nominal output voltage. The data associated with VOUT_MARGIN_HIGH and VOUT_MARGIN_LOW can be stored to non-volatile memory using the STORE_DEFAULT_ALL command. 

The module is commanded to go to the margined high or low voltages using the OPERATION command. Bits [5:2] are used to enable margining as follows: 

VOUT(OV_REQ) = (VOUT_OV_FAULT_LIMIT) X 2[-10                ] 

00XX : Margin Off 

0101 : Margin Low (Ignore Fault) 0110 : Margin Low (Act on Fault) 1001 : Margin High (Ignore Fault) 1010 : Margin High (Act on Fault) 

VOUT(UV_REQ) = (VOUT_UV_FAULT_LIMIT) X 2[-10                ] 

Values within the supported range for over and undervoltage detection thresholds will be set to the nearest fixed percentage. Note that the correct value for VOUT_SCALE_LOOP must be set in the module for the correct over or under voltage trip points to be calculated. 

## **PMBus Adjustable Overcurrent Warning** 

The module can provide an overcurrent warning via the PMBus. The threshold for the overcurrent warning can be set using the parameter 

IOUT_OC_WARN_LIMIT. This command uses the “Linear” data format with a two byte data word where the upper five bits [7:3] of the high byte represent the exponent and the remaining three bits of the high byte [2:0] and the eight bits in the low byte represent the mantissa. The exponent is fixed at –1 (decimal). The

## **Technical Specifications** (continued) 

## **PMBus Adjustable Output Over and Under Voltage Protection (continued)** 

## **Power Good** 

The module provides a Power Good (PGOOD) signal that is implemented with an open-drain output to indicate that the output voltage is within the regulation limits of the power module. The PGOOD signal will be de-asserted to a low state if any condition such as overtemperature, overcurrent or loss of regulation occurs that would result in the output voltage going outside the specified thresholds. The PGOOD thresholds are user selectable via the PMBus (the default values are as shown in the Feature Specifications Section). Each threshold is set up symmetrically above and below the nominal value. The POWER_GOOD_ON command sets the output voltage level above which PGOOD is asserted (lower threshold). For example, with a 1.2V nominal output voltage, the POWER_GOOD_ON threshold can set the lower threshold to 1.14 or 1.1V. Doing this will automatically set the upper thresholds to 1.26 or 1.3V. The POWER_GOOD_OFF command sets the level below which the PGOOD command is de-asserted. This command also sets two thresholds symmetrically placed around the nominal output voltage. Normally, the POWER_GOOD_ON threshold is set higher than the POWER_GOOD_OFF threshold. 

In addition to adjustable output voltage protection, the 6A Digital PicoDLynx[TM] module can also be programmed for the response to the fault. The VOUT_OV_FAULT RESPONSE and 

VOUT_UV_FAULT_RESPONSE commands specify the response to the fault. Both these commands use a single data byte with the possible options as shown below 

1. Continue operation without interruption (Bits [7:6]= 00, Bits [5:3] = xxx) 

2. Continue for four switching cycles and then shut down if the fault is still present, followed by no restart or continuous restart (Bits [7:6] = 01, Bits [5:3] = 000 means no restart, Bits [5:3] = 111 means continuous restart) 

3. Immediate shut down followed by no restart or continuous restart (Bits [7:6] = 10, Bits [5:3] = 000 means no restart, Bits [5:3] = 111 means continuous restart). 

4. Module output is disabled when the fault is present and the output is enabled when the fault no longer exists (Bits [7:6] = 11, Bits [5:3] = xxx). 

Note that separate response choices are possible for output over voltage or under voltage faults. 

Both POWER_GOOD_ON and POWER_GOOD_OFF commands use the “Linear” format with the exponent fixed at –10 (decimal). The two thresholds are given by 

## **PMBus Adjustable Input Undervoltage Lockout** 

The module allows adjustment of the input under voltage lockout and hysteresis. The command VIN_ON allows setting the input voltage turn on threshold, while the VIN_OFF command sets the input voltage turn off threshold. For the VIN_ON command, possible values are 2.75V, and 3V to 14V in 0.5V steps. For the VIN_OFF command, possible values are 2.5V to 14V in 0.5V steps. If other values are entered for either command, they will be mapped to the closest of the allowed values. 

## VOUT(PGOOD_ON) = (POWER_GOOD_ON) X 2[-10                ] 

VOUT(PGOOD_OFF) = (POWER_GOOD_OFF) X 2[-10                ] 

Both commands use two data bytes with bit [7] of the high byte fixed at 0, while the remaining bits are r/w and used to set the mantissa using two’s complement representation. Both commands also use the VOUT_SCALE_LOOP parameter so it must be set correctly. The default value of POWER_GOOD_ON is set at 1.1035V and that of the POWER_GOOD_OFF is set at 1.08V. The values associated with these commands can be stored in non-volatile memory using the STORE_DEFAULT_ALL command. 

VIN_ON must be set higher than VIN_OFF. Attempting to write either VIN_ON lower than VIN_OFF or VIN_OFF higher than VIN_ON results in the new value being rejected, SMBALERT being asserted along with the CML bit in STATUS_BYTE and the invalid data bit in STATUS_CML. 

The PGOOD terminal can be connected through a pullup resistor (suggested value 100K Ω ) to a source of 5VDC or lower. 

Both the VIN_ON and VIN_OFF commands use the “Linear” format with two data bytes. The upper five bits represent the exponent (fixed at -2) and the remaining 11 bits represent the mantissa. For the mantissa, the four most significant bits are fixed at 0.

## **Technical Specifications** (continued) 

## **Measurement of Output Current, Output Voltage and Input Voltage** 

The module is capable of measuring key module parameters such as output current and voltage and input voltage and providing this information through the PMBus interface. Roughly every 200 μ s, the module makes 16 measurements each of output current, voltage and input voltage. Average values of of these 16 measurements are then calculated and placed in the appropriate registers. The values in the registers can then be read using the PMBus interface. 

## **Measuring Output Current Using the PMBus** 

The module measures current by using the inductor winding resistance as a current sense element. The inductor winding resistance is then the current gain factor used to scale the measured voltage into a current reading. This gain factor is the argument of the IOUT_CAL_GAIN command, and consists of two bytes in the linear data format. The exponent uses the upper five bits [7:3] of the high data byte in two-s complement format and is fixed at –15 (decimal). The remaining 11 bits in two’s complement binary format represent the mantissa. 

The current measurement accuracy is also improved by each module being calibrated during manufacture with the offset in the current reading. The IOUT_CAL_OFFSET command is used to store and read the current offset. The argument for this command consists of two bytes composed of a 5-bit exponent (fixed at -4d) and a 11-bit mantissa. This command has a resolution of 62.5mA and a range of -4000mA to +3937.5mA. During manufacture, each module is calibrated by measuring and storing the current gain factor and offset into non-volatile storage. The READ_IOUT command provides module average output current information. This command only supports positive or current sourced from the module. If the converter is sinking current a reading of 0 is provided. The READ_IOUT command returns two bytes of data in the linear data format. The exponent uses the upper five bits [7:3] of the high data byte in two-s complement format and is fixed at –4 (decimal). The remaining 11 bits in two’s complement binary format represent the mantissa with the 11th bit fixed at 0 since only positive numbers are considered valid. 

Note that the current reading provided by the module is not corrected for temperature. The temperature corrected current reading for module temperature TModule  can be estimated using the following equation 

**==> picture [163 x 26] intentionally omitted <==**

where IOUT_CORR is the temperature corrected value of the current measurement, IREAD_OUT is the module current measurement value, TIND is the temperature of the inductor winding on the module. Since it may be difficult to measure TIND, it may be approximated by an estimate of the module temperature. 

## **Measuring Output Voltage Using the PMBus** 

The module can provide output voltage information using the READ_VOUT command. The command returns two bytes of data all representing the mantissa while the exponent is fixed at -10 (decimal). During manufacture of the module, offset and gain correction values are written into the non-volatile memory of the module. The command 

VOUT_CAL_OFFSET can be used to read and/or write the offset (two bytes consisting of a 16- bit mantissa in two’s complement format) while the exponent is always fixed at -10 (decimal). The allowed range for this offset correction is -125 to 124mV. The command VOUT_CAL_GAIN can be used to read and/or write the gain correction - two bytes consisting of a five-bit exponent (fixed at -8) and a  11-bit mantissa. The range of this correction factor is -0.125V to +0.121V, with a resolution of 0.004V. The corrected output voltage reading is then given by: 

VOUT (Final) = [VOUT (Initial) X (1 + VOUT_CAL_GAIN)] + VOUT_CAL_OFFSET 

## **Measuring Input Voltage Using the PMBus** 

The module can provide output voltage information using the READ_VIN command. The command returns two bytes of data in the linear format. The upper five bits [7:3] of the high data form the two’s complement representation of the exponent which is fixed at –5 (decimal). The remaining 11 bits are used for two’s complement representation of the mantissa, with the 11th bit fixed at zero since only positive numbers are valid.

## **Thermal Considerations** 

Power modules operate in a variety of thermal environments; however, sufficient cooling should always be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The test set-up is shown in Figure 49. The preferred airflow direction for the module is in Figure 50. 

The thermal reference points, Tref used in the specifications are also shown in Figure 50. For reliable operation the temperatures at these points should not exceed 120°C. The output power of the module should not exceed the rated power of the module (V ,set x Io,max). Please refer to the Application Note “Thermal Characterization Process For Open-Frame Board-Mounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures.

## **Technical Specifications** (continued) 

## **Shock and Vibration** 

The ruggedized (-D version) of the modules are designed to withstand elevated levels of shock and vibration to be able to operate in harsh environments. The ruggedized modules have been successfully tested to the following conditions: 

## **Non operating random vibration:** 

Random vibration tests conducted at 25[o] C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms (Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes. 

## **Operating shock to 40G per Mil Std. 810G, Method 516.4 Procedure I:** 

The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock impulse characteristics as follows: 

All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes. 

Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of 40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen shocks. 

## **Operating vibration per Mil Std 810G, Method 514.5 Procedure I:** 

The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810G, Method 514.5, and Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 1 and Table 2 for all axes. Full compliance with performance specifications was required during the performance test. No damage was allowed to the module and full compliance to performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD- 810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and endurance levels shown in Table 7 and Table 8 for all axes. The performance test has been split, with one half accomplished before the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least 16 minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours minimum per axis.

## **Technical Specifications** (continued) 

## **Surface Mount Information** 

## **Pick and Place** 

The 6A Digital PicoDLynx[TM] modules use an open frame construction and are designed for a fully automated assembly process. The modules are fitted with a label designed to provide a large surface area for pick and place operations. The label meets all the requirements for surface mount processing, as well as safety standards, and is able to withstand reflow temperatures of up to 300°C. The label also carries product information such as product code, serial number and the location of manufacture. 

## **Nozzle Recommendations** 

The module weight has been kept to a minimum by using open frame construction. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The minimum recommended inside nozzle diameter for reliable operation is 3mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 7 mm. 

## **Bottom Side / First Side Assembly** 

This module is not recommended for assembly on the bottom side of a customer board. If such an assembly is attempted, components may fall off the module during the second reflow process. 

## **Lead Free Soldering** 

The 12VDigital PicoDLynx[TM] 6A modules are lead-free (Pb- free) and RoHS compliant and are both forward and backward compatible in a Pb-free and a SnPb soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. 

## **Pb-free Reflow Profile** 

Power Systems will comply with J-STD-020 Rev. C (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package (table 5-2). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 51. Soldering outside of the recommended profile requires testing to verify results and performance. 

It is recommended that the pad layout include a test pad where the output pin is in the ground plane. The thermocouple should be attached to this test pad since this will be the coolest solder joints. The temperature of this point should be: 

Maximum peak temperature is 260°C. Minimum temperature is 235°C. Dwell time above 217°C: 60 seconds minimum Dwell time above 235°C: 5 to 15 second 

## **MSL Rating** 

The 6A Digital Pico SlimLynx[TM] Open Frame modules have a MSL rating of 2a 

## **Storage and Handling** 

The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. B (Handling, Packing, Shipping and Use of Moisture/ Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of ≤ 30°C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40° C, < 90% relative humidity.

## **Post Solder Cleaning and Drying Considerations** 

Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to Board Mounted Power Modules: Soldering and Cleaning Application Note (AN04-001).
