RTrim GND Licensed  ISO** 9001 and ISO 14001 certified manufacturing facilities Description TM The 3A Analog PicoDLynx power modules are non-isolated dc-dc converters that can deliver up to 3A 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 0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over TM current and over temperature protection. The Tunable Loop 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. * 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 December 14, 2017 ©2014 General Electric Company.

The power module has 0.51.5 2.53.5 4.5 extra-low voltage (ELV) outputs when all inputs are ELV.

Input ripple voltage for various output voltages positive input lead. 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. 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 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 TM Tunable Loop feature described later in this data sheet. December 14, 2017 ©2014 General Electric Company. All rights reserved.

Layout to support either Analog or Digital TM Tunable Loop PicoDLynx on the same pad. TM The 3A PicoDLynx modules have a feature that optimizes transient response of the module called TM Tunable Loop . 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. TM The Tunable Loop allows the user to externally adjust the voltage control loop to match the filter network connected to the output of the module. The Tunable TM Loop 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. VOUT SENSE RTUNE C O MODULE CTUNE TRIM RTrim GND Figure. 45. Circuit diagram showing connection of RTUME and CTUNE to tune the control loop of the module. Recommended values of R and C for different TUNE TUNE 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. 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 R and C in order to meet 2% output TUNE TUNE voltage deviation limits for some common output voltages in the presence of a 1.5A to 3A step change (50% of full load), with an input voltage of 12V.

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 46. The preferred airflow direction for the module is in Figure 47. 25.4_ Figure 47.

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-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.
