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 frequency oscillator,
under voltage lock-out, leading edge blanking, optimized gate
turn-on/turn-off driver, thermal shutdown protection, over
voltage protection, and temperature compensated precision
current sources for loop compensation and fault protection
circuitry. compared to discrete MOSFET and PWM controller
or R
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.
