Fairchild Power Switch(FPS)

Features

Description

• Wide operatimg frequency range up to (150kHz)

• Pulse by pulse over current limiting

• Over load protection

• Over voltage protecton (Min. 23V)

• Internal thermal shutdown function

• Under voltage lockout

• Internal high voltage sense FET

• External sync terminal

• Auto Restart Mode

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 control IC features a trimmed oscillator, under

voltage lock-out, leading edge blanking, optimized gate

turn-on/turn-off driver, thermal shut down protection, over

voltage protection, temperature compensated precision

current sources for loop compensation and fault protection

circuit. compared to discrete MOSFET and controller or

switching converter 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 C-TV power supply.
