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
controller IC. 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, temperature
compensated precision current sources for loop
compensation and fault protection circuit. compared to
discrete MOSFET and PWM controller or R
CC
solution, a
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.
