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. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. August 6, 2020 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., UL ANSI/UL* 62368-1 and CAN/CSA+ C22.2 No. 62368-1 Recognized, DIN VDE 0868-1/A11:2017 (EN623681:2014/A11:2017) For the converter output to be considered meeting the Requirements of safety extra-low voltage (SELV) or ES1, the input must meet SELV/ES1 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. (c)2015 General Electric Company. All rights reserved. Page 11 GE Energy Data Sheet 6A Austin MicroLynxIITM: 12V SIP Non-Isolated DC-DC Power Modules 8.3Vdc -14Vdc input; 0.75Vdc to 5.5Vdc output; 6A Output Current Feature Description VIN+ Remote On/Off Austin MicroLynxTM II 12V SIP power modules feature an On/Off pin for remote On/Off operation. Two On/Off logic options are available in the Austin MicroLynxTM II 12V series modules. Positive Logic On/Off signal, device code suffix "4", turns the module ON during a logic High on the On/Off pin and turns the module OFF during a logic Low. Negative logic On/Off signal, no device code suffix, turns the module OFF during logic High and turns the module ON during logic Low. For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 28. The On/Off pin is an open collector/drain logic input signal (Von/Off) that is referenced to ground. During a logic-high (On/Off pin is pulled high internal to the module) when the transistor Q1 is in the Off state, the power module is ON. Maximum allowable leakage current of the transistor when Von/off = VIN,max is 10A. Applying a logic-low when the transistor Q1 is turned-On, the power module is OFF. During this state VOn/Off must be less than 0.3V. When not using positive logic On/off pin, leave the pin unconnected or tie to VIN. VIN+ MODULE R2 ON/OFF + I ON/OFF I ON/OFF ON/OFF + VON/OFF PWM Enable R1 Q2 CSS Q1 R2 GND _ Figure 29. Circuit configuration for using negative logic On/OFF. 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. The typical average output current during hiccup is 2A. Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. Q2 R1 VON/OFF PWM Enable R3 Q1 Q3 CSS R4 GND MODULE Rpull-up _ Overtemperature Protection To provide over temperature protection in a fault condition, the unit relies upon the thermal protection feature of the controller IC. The unit will shutdown if the thermal reference point Tref2, (see Figure 33) exceeds 140oC (typical), but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restarts after it cools down. Figure 28. Circuit configuration for using positive logic On/OFF. For negative logic On/Off devices, the circuit configuration is shown is Figure 29. The On/Off pin is pulled high with an external pull-up resistor (typical Rpull-up = 68k, +/- 5%). When transistor Q1 is in the Off state, logic High is applied to the On/Off pin and the power module is Off. The minimum On/off voltage for logic High on the On/Off pin is 2.5 Vdc. To turn the module ON, logic Low is applied to the On/Off pin by turning ON Q1. When not using the negative logic On/Off, leave the pin unconnected or tie to GND.

Feature Descriptions (continued) Output Voltage Programming The output voltage of the Austin MicroLynxTM II 12V SIP can be programmed to any voltage from 0.75Vdc to 5.5Vdc by connecting a resistor (shown as Rtrim in Figure 30) between Trim and GND pins of the module. Without an external resistor between Trim and GND pins, the output of the module will be 0.7525Vdc. To calculate the value of the trim resistor, Rtrim for a desired output voltage, use the following equation: 10500 Rtrim = - 1000 Vo - 0.7525 The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using the trim feature, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Pmax = Vo,set x Io,max). Voltage Margining Rtrim is the external resistor in Vo is the desired output voltage For example, to program the output voltage of the Austin MicroLynxTM 12V module to 1.8V, Rtrim is calculated as follows: 10500 - 1000 1 . 8 - 0 . 7525 Rtrim = Rtrim = 9.024k Output voltage margining can be implemented in the Austin MicroLynxTM II modules by connecting a resistor, Rmargin-up, from Trim pin to ground pin for margining-up the output voltage and by connecting a resistor, Rmargindown, from Trim pin to Output pin. Figure 31 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at www.gecriticalpower.com under the Design Tools section, also calculates the values of Rmargin-up and Rmargin-down for a specific output voltage and % margin.

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 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 volt basis. By connecting multiple modules together, customers can get multiple modules to 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 of 10msec delay is required before applying voltage on the SEQ pin. During this time, potential of 50mV ( 10 mV) is maintained on the SEQ pin. After 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 output reaches the set-point voltage. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. 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 to ensure a controlled shutdown of the modules. When using the EZ-SEQUENCETM feature to control start-up of the module, pre-bias immunity feature during start-up is disabled. The pre-bias immunity feature of the module relies on the module being in the diode-mode during startup. When using the EZ-SEQUENCETM feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when voltage at the SEQ pin is applied. This will result in sinking current in the module if pre-bias voltage is present at the output of the module. When pre-bias immunity during start-up is required, the EZSEQUENCETM feature must be disabled. For additional guidelines on using EZ-SEQUENCETM feature of Austin MicroLynxTM II 12V, contact your GE technical representative for preliminary application note on output voltage sequencing using Austin Lynx II series.

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 33. Note that the airflow is parallel to the long axis of the module as shown in Figure 32. The derating data applies to airflow in either direction of the module's long axis. 76.2_ (3.0) x Air Flow 7.24_ (0.285) Tref1 (inductor winding) Probe Location for measuring airflow and ambient temperature Air flow Figure 33. Thermal Test Set-up. Heat Transfer via Convection Top View Tref2 Increased airflow over the module enhances the heat transfer via convection.

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. Through-Hole Lead-Free Soldering Information The RoHS-compliant through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHScompliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process.
