Description
The Fairchild Power Switch(FPS) product family is specially designed for an off-line SMPS with minimal external components. 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 circuitry compared 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 is well suited for cost effective design of flyback converters.
