The Austin SuperLynxTM II 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 14, 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. Page 11 GE Energy Data Sheet Austin SuperLynxTMII: SIP Non-Isolated DC-DC Power Modules 2.4Vdc -5.5Vdc input; 0.75Vdc to 3.63Vdc output; 16A Output Current Feature Description VIN+ Remote On/Off Austin SuperLynxTM II SIP power modules feature an On/Off pin for remote On/Off operation. Two On/Off logic options are available in the Austin SuperLynxTM II 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 logiclow 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 + VON/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 3.5A. Input Undervoltage Lockout PWM Enable Q1 Q3 CSS 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. Overtemperature Protection R4 _ Figure 28. Remote On/Off Implementation. 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 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. January 14, 2016 I ON/OFF ON/OFF Q2 R1 R3 GND MODULE Rpull-up 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 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 restart after it cools down. (c)2016 General Electric Company. All rights reserved.

Without an external resistor between TRIM pin and the ground, the output voltage of the module is 0.7525 Vdc. To calculate the value of the resistor Rtrim for a particular output voltage Vo, use the following equation: 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 = Rtrim = 15.004k V O(+) V IN(+) 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 Output voltage margining can be implemented in the Austin SuperLynxTM II 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.

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 setpoint 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. 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.

Remote sense circuit configuration 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. 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 start-up. 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 EZ-SEQUENCETM feature must be disabled. For additional guidelines on using EZSEQUENCETM feature of Austin SuperLynxTM II, contact the GE technical representative for preliminary application note on output voltage sequencing using Austin Lynx II series. 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 January 14, 2016 Thermal Considerations (c)2016 General Electric Company.

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 34. Note that the airflow is parallel to the long axis of the module as shown in figure 33. The derating data applies to airflow in either direction of the module's long axis. 25.4_ (1.0) Wind Tunnel PWBs Power Mod ule 76.2_ (3.0) x 5.97_ (0.235) Prob e Loc a tion for mea suring a irflow a nd a m b ient tem p era ture Air flow Figure 34.

For reliable operation this temperature should not exceed 115oC. The output power of the module should not exceed the rated power of the module (Vo,set x Io,max). 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 temperatures (TA) for airflow conditions ranging from natural convection and up to 2m/s (400 ft./min) are shown in the Characteristics Curves section.

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 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.
