Terminal Description The Fairchild Power Switch(FPS) product family is specially designed for an off line SMPS with minimal external ponents. The Fairchild Power Switch(FPS) consist of high voltage power Sense FET and current mode PWM IC. Included PWM controller features integrated fixed oscillator, under voltage lock out, optimized gate turn on/turn off driver, thermal shut down protection, over voltage protection, and temperature pensated precision current sources for loop pensation and fault protection circuitry. pared to discrete MOSFET and controller or RCC switching converter solution, a Fairchild Power Switch(FPS) can reduce total ponent count, design size, and weight and at the same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for cost effective monitor power supply. TO-3P-5L 1. Drain 2. Gnd 3. VCC 4. Feed Back 5. Sync.
