## **Technical Specifications** (continued) 

## **Design Considerations** 

## **Input Filtering** 

The 3A Analog 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 3A of load current with 1x22µF or 2x22µF 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 (3A 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 10 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. 

and a full load current of 3A. For stable operation of the module, limit the capacitance to less than the maximum 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 1x10uF, 1x22uF, 1x47uF and 2x47uF ceramic capacitors at the output (3A 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., 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), the input must meet SELV 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 5A, 125VDC in the positive input lead. 

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.

## **Technical Specifications** (continued) 

## **Feature Descriptions** 

## **Remote On/Off** 

The 3A Analog 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, Q3 is ON, Q4 is OFF and the internal PWM Enable signal is pulled high and the module is ON. When transistor Q2 is turned ON, Q3 is OFF, Q4 turns ON pulling the ENABLE pin 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 modules can start into a prebiased output as long as the prebias voltage is 0.5V less than the set output voltage. 

## **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 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 12V. 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. 

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

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 14.4V input range is 20Kohms). When transistor Q1 is in the OFF state, the On/Off pin is pulled high, internal transistor Q4 is turned ON and the module is OFF. To turn the module ON, Q1 is turned ON pulling the On/Off pin low, turning transistor Q4 OFF resulting in the PWM Enable pin going high and the module turning ON.

## **Voltage Margining** 

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 technical representative for additional details. 

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

Without an external resistor between Trim and 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: 

**==> picture [139 x 27] intentionally omitted <==**

Rtrim is the external resistor in k Ω Vo is the desired output voltage. 

|**VO, set (V)**|**Rtrim(KΩ)**|
|---|---|
|0.6|Open|
|0.9|40|
|1.0|30|
|1.2|20|
|1.5|13.33|
|1.8|10|
|2.5|6.316|
|3.3|4.444|
|5.0|2.727|



**Table 1** 

## **Remote Sense** 

The power module has a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage at the SENSE pin.  The voltage between the SENSE pin and VOUT pin should not exceed 0.5V. 

**Figure 43. Circuit Configuration for margining Output voltage.** 

## **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. 

## **Overtemperature Protection** 

To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the overtemperature threshold of 135[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.

## **Technical Specifications** (continued) 

## **Feature Descriptions** (continued) 

## **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. 

## **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 ±10% outside the setpoint value. The PGOOD terminal can be connected through a pullup resistor (suggested value 100K Ω ) to a source of 5VDC or lower. 

## **Tunable Loop[TM ]** 

The 3A PicoDLynx[TM] modules have 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 SENSE and TRIM pins of the module, as shown in Fig. 45. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. 

## **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. 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 

**Figure. 45. 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 Tables 2 and 3. 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. 

**Figure 44. Layout to support either Analog or Digital PicoDLynx on the same pad.** 

In applications with tight output voltage limits in the presence of dynamic current loading, additional output capacitance will be required. 

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

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 6A to 12A step change (50% of full load), with an input voltage of 12V. 

thermal data presented here is based on physical measurements taken in a wind tunnel. The test set-up is shown in Figure 46. The preferred airflow direction for the module is in Figure 47.

The thermal reference points, Tref used in the specifications are also shown in Figure 47. 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 (Vo,set x Io,max).

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

## **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°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 4 and Table 5 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 12VAnalog PicoDLynx[TM] 3A 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** 

Only the -D version of this module can be placed at the bottom side of the customer board. No additional glue or adhesive is required is required to hold the module during the top side reflow process 

## **Lead Free Soldering** 

The 12VAnalog PicoDLynx[TM ] 3A 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). For questions regarding LGA, solder volume; please contact OmniOn for special manufacturing process instructions. 

The recommended linear reflow profile using Sn/Ag/ Cu solder is shown in Fig. 48. 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 12VAnalog PicoDLynx[TM] 3A 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.

## **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).
