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 19 shows the input ripple voltage for various output voltages at 40A of load current with 4x22 F, 6x22F or 8x22uF ceramic capacitors and an input of 12V.

Input ripple voltage for various output voltages with various external ceramic capacitors at the input (40A load). Input voltage is 12V. Scope Bandwidth limited to 20MHz Output Filtering 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 30A, 100V (for example, Littlefuse 456 series) in the positive input lead. These modules are designed for low output ripple voltage and will meet the maximum output ripple specification with 0.1 F ceramic and 47 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. 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 20 provides output ripple information for different external capacitance values at various Vo and a full load current of 40A. 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. July 22, 2019 (c)2012 General Electric Company. All rights reserved.

The 40A Analog MegaDLynxTM 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 21. For negative logic On/Off modules, the circuit configuration is shown in Fig. 22.. 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 2.0Vdc 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. 23. The Upper Limit curve shows that for output voltages lower than 0.8V, 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 4.5V.

This is accomplished via an additional sequencing pin. When not using the sequencing feature, leave it unconnected. 12 Rtrim = k (Vo - 0.6) Rtrim is the external resistor in k Vo is the desired output voltage. Table 1 provides Rtrim values required for some common output voltages. Table 1 VO, set (V) 0.6 0.9 1.0 1.2 1.5 1.8 Rtrim (K) Open 40 30 20 13.33 10 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. 26. 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. DLynx Module 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. V SEQ 20K SEQ R1=Rtrim Analog 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 25 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at www.GEpower.com under the Downloads section, also calculates the values of Rmarginup and Rmargin-down for a specific output voltage and % margin. Please consult your local GE technical representative for additional details. Vo Rmargin-down MODULE Q2 Trim Rmargin-up Rtrim 100 pF SIG_GND Figure 26. Circuit showing connection of the sequencing signal to the SEQ pin. 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 power-down. 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 setpoint voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential. Overcurrent Protection Q1 Figure 25. Circuit Configuration for margining Output voltage. 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. meet the required transient specification. For providing better noise immunity, we recommend that RTUNE value to be greater than 300. Some special considerations apply for design of converters in parallel operation: * When sizing the number of modules required for parallel operation, take note of the fact that current sharing has some tolerance. In addition, under transient conditions such as a dynamic load change and during startup, all converter output currents will not be equal. To allow for such variation and avoid the likelihood of a converter shutting off due to a current overload, the total capacity of the paralleled system should be no more than 90% of the sum of the individual converters. As an example, for a system of four MegaDLynxTM converters in parallel, the total current drawn should be less that 90% of (3 x 40A), i.e. less than 108 A. * All modules should be turned ON and OFF together. This is so that all modules come up at the same time avoiding the problem of one converter sourcing current into the other leading to an overcurrent trip condition. To ensure that all modules come up simultaneously, the on/off pins of all paralleled converters should be tied together and the converters enabled and disabled using the on/off pin. Note that this means that converters in parallel cannot be digitally turned ON as that does not ensure that all modules being paralleled turn on at the same time. * If digital trimming is used to adjust the overall output voltage, the adjustments need to be made in a series of small steps to avoid shutting down the output. Each step should be no more than 20mV for each module. For example, to adjust the overall output voltage in a setup with two modules (A and B) in parallel from 1V to 1.1V, module A would be adjusted from 1.0 to 1.02V followed by module B from 1.0 to 1.02V, then each module in sequence from 1.02 to 1.04V and so on until the final output voltage of 1.1V is reached. * If the Sequencing function is being used to start-up and shut down modules and the module is being held to 0V by the tracking signal then there may be small deviations on the module output. This is due to controller duty cycle limitations encountered in trying to hold the voltage down near 0V. * The share bus is not designed for redundant operation and the system will be non-functional upon failure of one of the units when multiple units are in parallel. In particular, if one of the converters shuts down during operation, the other converters may also shut down due to their outputs hitting current limit. In such a situation, unless a coordinated restart is ensured, the system may never properly restart since different converters will try to restart at different times causing an overload condition and subsequent shutdown. This situation can be avoided by having an external output voltage monitor circuit that detects a shutdown condition and forces all converters to shut down and restart together. 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. 27, 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. MODULE SYNC + GND Figure 27. External source connections to synchronize switching frequency of the module. Active Load Sharing (-P Option) For additional power requirements, the Mega DLynxTM power module is also equipped with paralleling capability. Up to five modules can be configured in parallel, with active load sharing. To implement paralleling, the following conditions must be satisfied. * All modules connected in parallel must be frequency synchronized where they are switching at the same frequency. This is done by using the SYNC function of the module and connecting to an external frequency source. Modules can be interleaved to reduce input ripple/filtering requirements. * The share pins of all units in parallel must be connected together. The path of these connections should be as direct as possible. * The remote sense connections to all modules should be made that to the same points for the output, i.e. all VS+ and VS- terminals for all modules are connected to the power bus at the same points. * For converters operating in parallel, tunable loop components "RTUNE" and "CTUNE" must be selected to July 22, 2019 (c)2012 General Electric Company.

Page 13 GE Data Sheet 40A Analog MegaDLynxTM: Non-Isolated DC-DC Power Modules 4.5Vdc -14.4Vdc input; 0.6Vdc to 2.0Vdc output; 40A Output Current 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 over-temperature, overcurrent or loss of regulation occurs that would result in the output voltage going outside the specified thresholds. The default value of PGOOD ON thresholds are set at 8% of the nominal Vset value, and PGOOD OFF thresholds are set at 10% of the nominal Vset. For example, if the nominal voltage (Vset) is set at 1.0V, then the PGOOD ON thresholds will be active anytime the output voltage is between 0.92V and 1.08V, and PGOOD OFF thresholds are active at 0.90V and 1.10V respectively. The PGOOD terminal can be connected through a pull-up resistor (suggested value 100K) to a source of 5VDC or lower. Dual Layout Identical dimensions and pin layout of Analog and Digital MegaDLynx 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. Tunable LoopTM The module has a feature that optimizes transient response of the module called Tunable LoopTM. External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise and to reduce output voltage deviations from the steadystate 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 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. 28. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. VOUT VS+ 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.

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 29. The preferred airflow direction for the module is in Figure 30. RTune MODULE 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 20A to 40A step change (50% of full load), with an input voltage of 12V.

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 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.

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.
