The Fairchild Power Switch(FPS) consist of high voltage power SenseFET and current mode PWM IC. Included PWM controller features integrated fixed oscillator, under voltage lock out, leading edge blanking, optimized gate turn-on/ turn-off driver, thermal shut down protection, over voltage protection, and temperature compensated precision current sources for loop compensation and fault protection circuitrycompared to discrete MOSFET and controller or RCC switching converter solution. The Fairchild Power Switch(FPS) can reduce total component count, design size, weight and at the same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for cost-effective design in either a flyback converter or a forward converter. TO-220F-4L 8-DIP TO220-5L 1 1 1. GND 2. Drain 3. Vcc 4. FB 1.6.7.8. Drain 2. GND 3.
