Fairchild Power Switch(FPS)

Features

Description

• Precision Fixed Operating Frequency (70kHz)

• Low Start-up Current(Typ. 100uA)

• 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

• Over Current Protection

• Over Voltage Protection (Min. 25V)

• Internal Thermal Shutdown Function

• Under Voltage Lockout

frequency oscillator, under voltage lock-out, leading edge

blanking, optimized gate turn-on/turn-off driver, thermal

shutdown protection, over voltage protection, and

• Internal High Voltage Sense FET

• Latch Mode

temperature compensated precision current sources for

loop compensation and fault protection circuitry. compared

to discrete MOSFET and PWM controller 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.
