Fairchild Power Switch(FPS)

Features

Description

• Precision Fixed Operating Frequency (70kHz)

• Low Start-up Current (Typ. 100µA)

• Pulse by Pulse Current Limiting

• Over Load Protection

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 frequency oscillator,

under voltage lock-out, leading edge blanking, 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 to discrete MOSFET and PWM controller

• Over Current Protection

• Over Voltage Protection (Min. 25V)

• Internal Thermal Shutdown Function

• Under Voltage Lockout

• Internal High Voltage Sense FET

• Auto-Restart Mode

or R

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 design in

either a flyback converter or a forward converter.
