An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of a complex power architecture. 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 fast-acting fuse with a maximum rating of 15 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used.

Two On/Off logic options are ON/OFF TM available in the Austin SuperLynx II series modules. Positive + PWM Enable Logic On/Off signal, device code suffix “4”, turns the module ON V ON/OFF R1 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 Q2 CSS module ON during logic Low. Q1 R2 For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 27. The On/Off pin is an open GND _ collector/drain logic input signal (Von/Off) that is referenced to ground. During a logic-high (On/Off pin is pulled high internal to Figure 28. Circuit configuration for using negative the module) when the transistor Q1 is in the Off state, the power logic On/OFF. module is ON. Maximum allowable leakage current of the transistor when Von/off = V is 10µA. Applying a logic-low IN,max when the transistor Q1 is turned-On, the power module is OFF. Overcurrent Protection During this state VOn/Off must be less than 0.3V. When not To provide protection in a fault (output overload) using positive logic On/off pin, leave the pin unconnected or tie condition, the unit is equipped with internal to V IN. current-limiting circuitry and can endure current limiting continuously.

For negative logic On/Off devices, the circuit configuration is shown is Figure 28. 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.

When an analog voltage is applied to the SEQ pin, the output Rdistribution Rcontact Rcontact Rdistribution V (+) V IN O voltage tracks this voltage until the output reaches the set-point voltage. The SEQ voltage must be set higher than the set-point Sense voltage of the module. The output voltage follows the voltage R LOAD 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 Rdistribution Rcontact Rcontact Rdistribution pin. COM COM Figure 31. 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 to ensure a controlled shutdown of the modules. TM When using the EZ-SEQUENCE 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 TM using the EZ-SEQUENCE 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 TM during start-up is required, the EZ-SEQUENCE feature must be TM disabled. For additional guidelines on using EZ-SEQUENCE TM feature of Austin SuperLynx II 12V, contact GE technical representative for preliminary application note on output voltage sequencing using Austin Lynx II series. Remote Sense TM The Austin SuperLynx II 12V 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 31). The voltage between the Sense pin and Vo pin must not exceed 0.5V. August 19, 2016 ©2012 General Electric Company. All rights reserved.

Considerations include ambient temperature, airflow, module PWBs power dissipation, and the need for increased reliability. A Power Module 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.

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 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb- free reflow process.
