Fairchild Power Switch(FPS)

Features

Description

• Wide Operating Frequency Range up to 150KHz

• Internal Burst Mode Controller for Stand-by Mode

• Pulse by Pulse Over Current Limiting

• Over Current Protection(Auto Restart Mode)

• Over Voltage Protection (Auto Restart Mode)

• Over Load Protection(Auto Restart Mode)

• Internal Thermal Shutdown Function(Auto Restart Mode)

• Under Voltage Lockout

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.
