Description

The Fairchild Power Switch(SPS) product family is specially

designed for an off-line SMPS with minimal external

components. The Fairchild Power Switch(SPS) 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, a Fairchild Power

Switch(SPS) 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 LCD monitor power supply.
