Fairchild Power Switch(FPS)
Features
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) consists of a
high voltage power SenseFET and a current mode PWM IC.
Included PWM controller integrates the fixed frequency
oscillator, the under voltage lock-out, the leading edge
blanking, the optimized gate turn-on/turn-off driver, the
thermal shutdown protection, the over voltage protection,
and the temperature compensated precision current sources
for the loop compensation and the fault protection circuitry.
Compared to a discrete MOSFET and a PWM controller or
an RCCsolution, a Fairchild Power Switch(FPS) can reduce
the total component count, design size and weight and at the
same time increase efficiency, productivity, and system
reliability. It has a basic platform well suited for the cost
effective design in either a flyback converter or a forward
converter
