These modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely regulated output voltage from 0.59Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current and over temperature protection, and output voltage sequencing (APTS versions). The Ruggedized version (-D) is capable of operation up to 105°C and withstand high levels of shock and vibration. A new feature, the Tunable Loop[TM] , 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. > * _UL_ is a registered trademark of Underwriters Laboratories, Inc. > † _CSA_ is a registered trademark of Canadian Standards Association. > ‡ _VDE_ is a trademark of Verband Deutscher Elektrotechniker e.V. > ** ISO is a registered trademark of the International Organization of Standards ©2013 General Electric Company.

These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability. |**Parameter**|**Device**|**Symbol**|**Min**|**Max**|**Unit**| |---|---|---|---|---|---| |Input Voltage<br>Continuous|All|VIN|-0.3|15|Vdc| |Sequencing Voltage|APTS|VSEQ|-0.3|ViN|Vdc| |Operating Ambient Temperature<br>(see Thermal Considerations section)|All<br>-D version|TA<br>TA|-40<br>-40|85<br>105|°C<br>°C| |Storage Temperature|All|Tstg|-55|125|°C| ## **Electrical Specifications** Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions. |**Parameter**|**Device**|**Symbol**|**Min**|**Typ**|**Max**|**Unit**| |---|---|---|---|---|---|---| |Operating Input Voltage|All|VIN|4.5|⎯|14.0|Vdc| |Maximum Input Current<br>(VIN=4.5V to 14V, IO=IO, max)|All|IIN,max|||6.5|Adc| |Input No Load Current<br>(VIN= 12.0Vdc, IO= 0, module enabled)|VO,set= 0.6 Vdc|IIN,No load||16||mA| ||VO,set= 3.3Vdc|IIN,No load||55||mA| |Input Stand-by Current<br>(VIN= 12.0Vdc, module disabled)|All|IIN,stand-by||1.2||mA| |Inrush Transient|All|I2t|||1|A2s| |Input Reflected Ripple Current, peak-to-peak<br>(5Hz to 20MHz, 1μH source impedance; VIN=0 to 14V,<br>IO= IOmax; See Test Configurations)|All|||86||mAp-p| |Input Ripple Rejection (120Hz)|All|||50||dB| ## **CAUTION: This power module is not internally fused. An input line fuse must always be used.** This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 6A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information. ©2013 General Electric Company.

Output Voltage and Efficiency Test Setup.** **==> picture [142 x 22] intentionally omitted <==** ## **Design Considerations** ## **Input Filtering** The 12V Pico TLynx[TM] 6A 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 40 shows the input ripple voltage for various output voltages at 6A of load current with 1x10 µF or 1x22 µF ceramic capacitors and an input of 12V. **==> picture [205 x 147] intentionally omitted <==** **----- Start of picture text -----**<br> 450<br>400 1x10uF<br>350 1x22uF<br>300<br>250<br>200<br>150<br>100<br>50<br>0<br>0.5 1 1.5 2 2.5 3 3.5 4 4.5 5<br>Output Voltage (Vdc)<br>Input Ripple Voltage (mVp-p)<br>**----- End of picture text -----**<br> **Figure 40. Input ripple voltage for various output voltages with 1x10 µF or 1x22 µF ceramic capacitors at the input (6A load). Input voltage is 12V.** ## **Output Filtering** The 12V Pico TLynx[TM] 6A 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. 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 41 provides output ripple information for different external capacitance values at various Vo and for a load current of 6A. 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. ©2013 General Electric Company.

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 6A in the positive input lead. ## **Feature Descriptions** ## **Remote Enable** The 12V Pico TLynx[TM] 6A 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 is 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 42. When the external transistor Q1 is in the OFF state, the internal PWM Enable signal is pulled high through an internal 1.5M Ω resistor and the external pullup resistor and the module is ON. When transistor Q1 is turned ON, the On/Off pin is pulled low and the module is OFF. A suggested value for Rpullup is 20k Ω . **==> picture [194 x 150] intentionally omitted <==** **----- Start of picture text -----**<br> VIN+<br>MODULE<br>Rpullup 1.5MEG<br>I<br>ON/OFF<br>+ 2.05K PWM Enable<br>ON/OFF<br>V<br>ON/OFF<br>Q1<br>GND _<br>**----- End of picture text -----**<br> **Figure 42. Circuit configuration for using positive On/Off logic.** For negative logic On/Off modules, the circuit configuration is shown in Fig. 43. The On/Off pin should be pulled high with an external pull-up resistor (suggested value for the 4.5V 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 turned ON pulling the On/Off pin low, turning transistor Q1 OFF resulting in the PWM Enable pin going high. ©2013 General Electric Company. All rights reserved.

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. **==> picture [207 x 141] intentionally omitted <==** **----- Start of picture text -----**<br> 16<br>14<br>12<br>Upper Limit<br>10<br>8<br>6<br>4<br>2 Lower Limit<br>0<br>0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 5.5 6<br>Output Voltage (V)<br>Input Voltage (v)<br>**----- End of picture text -----**<br> **Figure 44. Output Voltage vs. Input Voltage Set Point Area plot showing limits where the output voltage can be set for different input voltages.** Without an external resistor between Trim and GND pins, the output of the module will be 0.59Vdc. To calculate the value of the trim resistor, _Rtrim_ for a desired output voltage, use the following equation: **==> picture [107 x 28] intentionally omitted <==** Rtrim is the external resistor in kΩ ## **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 140[o] C is exceeded at the thermal reference point Tref . The thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. ## **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. ## **Output Voltage Programming** The output voltage of the 12V Pico TLynx[TM] 6A modules can be programmed to any voltage from 0.59dc 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. 44. The Upper Limit curve shows that for output voltages of 0.9V and lower, the input voltage must be lower than the maximum of 14V. The Lower Limit curve shows that for output voltages of 3.8V and higher, the input voltage needs to be larger than the minimum of 4.5V. _Vo_ is the desired output voltage. Table 1 provides Rtrim values required for some common output voltages. **Table 1** |**VO, set (V)**|**_Rtrim(_KΩ)**| |---|---| |0.6|656.7| |1.0|14.45| |1.2|9.704| |1.5|6.502| |1.8|4.888| |2.5|3.096| |3.3|2.182| |5.0|1.340| By using a ±0.5% tolerance trim resistor with a TC of ±100ppm, a set point tolerance of ±1.5% can be achieved as specified in the electrical specification. ## **Remote Sense** The 12V Pico TLynx[TM] 6A power modules have 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 must not exceed 0.5V. Note that the output voltage of the module cannot exceed the specified maximum value. This includes the voltage drop between the SENSE and Vout pins. When the Remote Sense feature is not being used, connect the SENSE pin to the VOUT pin **.** ©2013 General Electric Company.

Figure 46 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at www.lineagepower.com under the Design Tools section, also calculates the values of Rmargin-up and Rmargin-down for a specific output voltage and % margin.

Circuit Configuration for margining Output voltage.** ## **Monotonic Start-up and Shutdown** The 12V Pico TLynx[TM] 6A modules have monotonic startup and shutdown behavior for any combination of rated input voltage, output current and operating temperature range. ## **Startup into Pre-biased Output** The 12V Pico TLynx[TM] 6A modules can start into a prebiased output as long as the prebias voltage is 0.5V less than the set output voltage. Note that prebias operation is not supported when output voltage sequencing is used. ## **Output Voltage Sequencing** The 12V Pico TLynx[TM] 6A modules include 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, either tie the SEQ pin to VIN or leave it unconnected. When an analog 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 SEQ voltage must be set higher than the set-point voltage of the module. The output voltage follows the voltage on the SEQ pin 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. For proper voltage sequencing, first, input voltage is applied to the module. The On/Off pin of the module is left unconnected (or tied to GND for negative logic modules or tied to VIN for positive logic modules) so that the module is ON by default. After applying input voltage to the module, a minimum 10msec delay is required before applying voltage on the SEQ pin. This delay gives the module enough time to complete its internal powerup soft-start cycle. During the delay time, the SEQ pin should be held close to ground (nominally 50mV ± 20 mV). This is required to keep the internal op-amp out of saturation thus preventing output overshoot during the start of the sequencing ramp. By selecting resistor R1 (see fig. 47) according to the following equation **==> picture [92 x 25] intentionally omitted <==** the voltage at the sequencing pin will be 50mV when the sequencing signal is at zero. ©2013 General Electric Company. All rights reserved. May 2, 2013 _Page 15_ GE Data Sheet ## 12V PicoTLynx[TM] 6A: Non-Isolated DC-DC Power Modules **4.5Vdc –14Vdc input; 0.59Vdc to 5.5Vdc output; 6A Output Current** **==> picture [177 x 143] intentionally omitted <==** **----- Start of picture text -----**<br> MODULE<br>VIN+<br>499K<br>+<br>OUT<br>R1<br>SEQ -<br>10K<br>GND<br>**----- End of picture text -----**<br> **Figure 47. Circuit showing connection of the sequencing signal to the SEQ pin.** After the 10msec delay, an analog voltage is applied to the SEQ pin and the output voltage of the module will track this voltage on a one-to-one volt bases until the output reaches the setpoint voltage. 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. When using the EZ-SEQUENCE[TM] feature to control start-up of the module, pre-bias immunity during start-up is disabled. The pre-bias immunity feature of the module relies on the module being in the diode-mode during start-up. When using the EZSEQUENCE[TM] feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when the voltage at the SEQ pin is applied. This will result in the module sinking current if a pre-bias voltage is present at the output of the module. When pre-bias immunity during start-up is required, the EZ-SEQUENCE[TM] feature must be disabled. For additional guidelines on using the EZ-SEQUENCE[TM] feature please refer to Application Note AN04-008 “Application Guidelines for Non-Isolated Converters: Guidelines for Sequencing of Multiple Modules”, or contact the GE technical representative for additional information. External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise (see Fig. 41) 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. 48. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. **==> picture [164 x 131] intentionally omitted <==** **----- Start of picture text -----**<br> VOUT<br>SENSE<br>RTUNE<br>MODULE C O<br>CTUNE<br>TRIM<br>GND RTrim<br>**----- End of picture text -----**<br> **Figure. 48. Circuit diagram showing connection of RTUME and CTUNE to tune the control loop of the module.** ## **Power Good** The 12V Pico TLynx[TM] 6A modules provide 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 should be connected through a pullup resistor (suggested value 100K Ω ) to a source of 5VDC or lower. ## **Tunable Loop[TM ]** The 12V Pico TLynx[TM] 6A modules have a new feature that optimizes transient response of the module called Tunable Loop[TM] . ©2013 General Electric Company.

Table 2 shows the recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 470uF 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 GE 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 or input voltages other than 12V. ## **Table 2.

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. **==> picture [187 x 190] intentionally omitted <==** **----- Start of picture text -----**<br> 25.4_<br>Wind Tunnel (1.0)<br>PWBs<br>Power Module<br>76.2_<br>(3.0)<br>x<br>Probe Location<br>for measuring<br>12.7_ airflow and<br>(0.50) ambient<br>temperature<br>Air<br> flow<br>**----- End of picture text -----**<br> **Figure 50. Preferred airflow direction and location of hot-spot of the module (Tref).** Modules marked ruggedized with a “D” suffix operate up to an ambient of 105 ° C. For the remaining types derating curves for individual output voltages meet existing specifications up to 85 ° C. **Figure 49. Thermal Test Setup.** 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[o] C. The output power of the module should not exceed the rated power of the module (Vo,set x Io,max).

The ruggedized modules have been successfully tested to the following conditions: ## **Non operating random vibration:** Random vibration tests conducted at 25C, 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. 810F, 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 810F, Method 514.5 Procedure I:** The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810F, 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-STD810, 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. **Table 4: Performance Vibration Qualification - All Axes** |**Frequency (Hz)**|**PSD Level**<br>**(G2/Hz)**|**Frequency (Hz)**|**PSD Level**<br>**(G2/Hz)**|**Frequency (Hz)**|**PSD Level**<br>**(G2/Hz)**| |---|---|---|---|---|---| |10|1.14E-03|170|2.54E-03|690|1.03E-03| |30|5.96E-03|230|3.70E-03|800|7.29E-03| |40|9.53E-04|290|7.99E-04|890|1.00E-03| |50|2.08E-03|340|1.12E-02|1070|2.67E-03| |90|2.08E-03|370|1.12E-02|1240|1.08E-03| |110|7.05E-04|430|8.84E-04|1550|2.54E-03| |130|5.00E-03|490|1.54E-03|1780|2.88E-03| |140|8.20E-04|560|5.62E-04|2000|5.62E-04| **Table 5: Endurance Vibration Qualification - All Axes** |**Frequency (Hz)**|**PSD Level**<br>**(G2/Hz)**|**Frequency (Hz)**|**PSD Level**<br>**(G2/Hz)**|**Frequency (Hz)**|**PSD Level**<br>**(G2/Hz)**| |---|---|---|---|---|---| |10|0.00803|170|0.01795|690|0.00727| |30|0.04216|230|0.02616|800|0.05155| |40|0.00674|290|0.00565|890|0.00709| |50|0.01468|340|0.07901|1070|0.01887| |90|0.01468|370|0.07901|1240|0.00764| |110|0.00498|430|0.00625|1550|0.01795| |130|0.03536|490|0.01086|1780|0.02035| |140|0.0058|560|0.00398|2000|0.00398| ©2013 General Electric Company.

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[o] 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. ## **Lead Free Soldering** The 12V Pico TLynx[TM] 6A modules are lead-free (Pb-free) and RoHS compliant and fully compatible in a Pb-free 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. **==> picture [201 x 127] intentionally omitted <==** **----- Start of picture text -----**<br> 300<br>Per J-STD-020 Rev.

Recommended linear reflow profile using Sn/Ag/Cu solder.** ## **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). ## **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 4-2). 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. ## **MSL Rating** The 12V Pico TLynx[TM] 6A 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. A (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-STD033A). 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. ©2013 General Electric Company.
