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 20A, fast-acting, glass type fuse rated for 32V (see Safety Considerations section).

The Austin SuperLynxTM SIP module is designed for low output ripple voltage and will meet the maximum output ripple specification with 1 F ceramic and 10 F tantalum 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. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. January 20, 2016 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 20A in the positive input lead. (c)2016 General Electric Company. All rights reserved.

The On/Off pin is pulled high with an external pull-up resistor (typical Rpull-up = 68k, 5%) as shown in Fig. 28. 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 1.5Vdc. 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. 21070 Rtrim = - 5110 Vo - 0 . 7525 For example, to program the output voltage of the Austin SuperLynxTM module to 1.8 Vdc, Rtrim is calculated is follows: 21070 - 5110 1.8 - 0.7525 Rtrim = VIN+ Rtrim = 15.004k MODULE Rpull-up I ON/OFF ON/OFF VON/OFF V IN(+) V O(+) ON/OFF TRIM PWM Enable + R1 Q2 CSS LOAD Q1 R trim R2 GND GND _ Figure 28. Circuit configuration for 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 3.5A. 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. Figure 29. Circuit configuration to program output voltage using an external resistor. The Austin SuperLynxTM can also be programmed by applying a voltage between the TRIM and GND pins (Figure 30). The following equation can be used to determine the value of Vtrim needed to obtain a desired output voltage Vo: Vtrim = (0.7 - 0.1698 x {Vo - 0.7525}) For example, to program the output voltage of a SuperLynxTM module to 3.3 Vdc, Vtrim is calculated as follows: Vtrim = (0.7 - 0.1698 x {3.3 - 0.7525}) Vtrim = 0.2670V Overtemperature Protection To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference point Tref, exceeds 125oC (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. Output Voltage Programming The output voltage of the Austin SuperLynxTM SIP can be programmed to any voltage from 0.75 Vdc to 3.63 Vdc by connecting a single resistor (shown as Rtrim in Figure 29) between the TRIM and GND pins of the module. Without an external resistor between the TRIM pin and the ground, the output voltage of the module is 0.7525 Vdc. To calculate the January 20, 2016 (c)2016 General Electric Company.

Q1 GND Figure 31. Circuit Configuration for margining Output voltage. Remote Sense The Austin SuperLynxTM SIP power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage at the Remote Sense pin (See Figure 32). The voltage between the Sense pin and Vo pin must not exceed 0.5V. The amount of power delivered by the module is defined as the output voltage multiplied by the output current (Vo x Io). When using Remote Sense the output voltage of the module can increase, which if the same output is maintained, increases the power output by the module. Make sure that the maximum output power of the module remains at or below the maximum rated power. When the Remote Sense feature is not being used, connect the Remote Sense pin to the output pin of the module.

Remote sense circuit configuration Voltage Margining Output voltage margining can be implemented in the Austin SuperLynxTM modules 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 the Output pin for margining-down. 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.

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 Fig. 33. Note that the airflow is parallel to the long axis of the module as shown in Fig. 34. The derating data applies to airflow in either direction of the module's long axis. Figure 34. Tref Temperature measurement location 25.4_ (1.0) Wind Tunnel PWBs Power Mod ule 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. 76.2_ (3.0) x 5.97_ (0.235) Post solder Cleaning and Drying Considerations Prob e Loc a tion for mea suring a irflow a nd a m b ient tem p era ture Air flow Figure 33. Thermal Test Set-up. The thermal reference point, Tref used in the specifications is shown in Figure 33. For reliable operation this temperature should not exceed 115 oC. The output power of the module should not exceed the rated power of the module (Vo,set x Io,max). Please refer to the Application Note "Thermal Characterization Process For Open-Frame Board-Mounted Power Modules" for a detailed discussion of thermal aspects including maximum device temperatures. 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 RoHS-compliant 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 Pbfree reflow process. If additional information is needed, please consult with your GE technical representative for more details. Heat Transfer via Convection Increased airflow over the module enhances the heat transfer via convection. Thermal derating curves showing the maximum output current that can be delivered at different local ambient temperature (TA) for airflow conditions ranging from natural convection and up to 2m/s (400 ft./min) are shown in the Characteristics Curves section.
