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 31 shows the input ripple voltage for various output voltages at 7A of load current with 2x22 F or 4x22 F ceramic capacitors and an input of 12V. 25 2x47uF Ext Cap 4x47uF Ext Cap 6x47uF Ext Cap 20 15 10 5 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 Output Voltage(Volts) 200 Input Ripple Voltage (mVp-p) Output Ripple (mVp-p) Design Considerations 2x22uF 160 Figure 38.

Input ripple voltage for various output voltages with 2x22 F or 4x22 F ceramic capacitors at the input (7A 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 F ceramic and 3x22 F 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. 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 60950-1 2nd Revised October 14, 2014, CSA C22.2 No. 60950-1-07, Second Ed. + A2:2014 (MOD), DIN EN 609501:2006 + A11:2009 + A1:2010 +A12:2011, + A2:2013 (VDE0805 Teil 1: 2014-08)(pending). 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. An external 20A Littelfuse 456 series fast-acting fuse or equivalent is recommended on the ungrounded 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 32 provides output ripple information for different external capacitance values at various Vo and a full load current of 7A. 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 LoopTM feature described later in this data sheet. November 14, 2018 (c)2017 General Electric Company. All rights reserved. Page 12 GE Data Sheet 7A Analog PicoDLynxIITM: Non-Isolated DC-DC Power Modules 4.5Vdc -14.4Vdc input; 0.6Vdc to 5.5Vdc output; 7A Output Current Analog Feature Descriptions Remote On/Off The 7A Analog PicoDLynxIITM 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 Q1 is in the OFF state, the internal PWM #Enable is pulled up internally, thus turning the module ON. When transistor Q1 is turned ON, the On/Off pin is pulled low, and consequently the internal PWM Enable signal is pulled low and the module is OFF. 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. When transistor Q2 is in the OFF state, the On/Off pin is pulled high, which pulls the internal ENABLE# High and the module is OFF. To turn the module ON, Q2 is turned ON pulling the On/Off pin low resulting in the PWM ENABLE# pin going Low. The typical voltage allowed on the On/Off pin is 7V. If Vin is used as a source, then a suitable external resistor R1 must be used to ensure that the voltage on the On/Off pin does not exceed 7V. 6.5V DLYNXII MODULE 40.2K I DLYNXII MODULE Vin R1 I ON/OFF ENABLE + V ON/OFF Q2 _ 3.09K GND 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. 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. 35. 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 3.3V, the input voltage needs to be higher than the minimum of 4.5V. ON/OFF ENABLE Q1 GND Figure 39.

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. To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shut down if the over-temperature threshold of 120C (typ) is exceeded at the thermal reference point Tref. Please refer to Electrical characteristic table, over-temperature section on page 5. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. The Tunable LoopTM allows the user to externally adjust the voltage control loop to match the filter network connected to the output of the module. The Tunable LoopTM is implemented by connecting a series R-C between the VS+ and TRIM pins of the module, as shown in Fig. 46. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. 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. 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. VOUT VS+ RTune MODULE Synchronization CO CTune 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 module switches at half the SYNC frequency. The Electrical Specifications table specifies the requirements of the external SYNC signal. If the SYNC pin is not used, the module will free run at the default switching frequency. If synchronization is not being used, connect the SYNC pin to Sig_GND. MODULE SYNC + SIG_GND Figure 45. External source connections to synchronize switching frequency of the module. Dual Layout Identical dimensions and pin layout of Analog and Digital PicoDLynxII modules permit migration from one to the other without needing to change the layout. In both cases the trim resistor is connected between trim and signal ground. The output of the analog module cannot be trimmed down to 0.51V Tunable LoopTM TRIM RTrim SIG_GND GND Figure. 46. Circuit diagram showing connection of RTUME 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 3 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 3 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 3.5A to 7A 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. The module has a feature that optimizes transient response of the module called Tunable LoopTM. November 14, 2018 (c)2017 General Electric Company. All rights reserved.

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 48. The preferred airflow direction for the module is in Figure 49. The thermal reference points, Tref used in the specifications are also shown in Figure 49. For reliable operation the temperatures at these points should not exceed 120oC. 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. 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 4 and Table 5 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.

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 300oC. 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 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. 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 30C 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. 300 Per J-STD-020 Rev.

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). For questions regarding Land grid array(LGA) soldering, solder volume; please contact GE for special manufacturing process instructions. The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 44. Soldering outside of the recommended profile requires testing to verify results and performance.
