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, 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 with
discrete MOSFET and controller or RCC switching converter
solution, the Fairchild Power Switch(FPS) can reduce 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 cost effective monitor
power supply.
