The Fairchild Power Switch(FPS) consist of highvoltage power SenseFET and current mode PWM IC. IncludedPWM 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 currentsources 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 thesame time increase efficiency, productivity, and system reliability. It is well suited for cost effective design of flyback converters.TO-220F-4L8-DIP11. GND2. Drain3. Vcc4. FB11.6.7.8. Drain2. GND3. Vcc4. FB5.
