Fairchild Power Switch(FPS)

Features

Description

• Precision Fixed Operating Frequency (100/67/50kHz)

• Low Start-up Current(Typ. 100uA)

• Pulse by Pulse Current Limiting

• Over Current Protection

• Over Voltage Protection (Min. 25V)

• Internal Thermal Shutdown Function

• 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) consists of a

high voltage power SenseFET and a current mode PWM IC.

Included PWM controller integrates the fixed frequency

oscillator, the under voltage lock-out, the leading edge

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

thermal shutdown protection, the over voltage protection,

and the temperature compensated precision current sources

for the loop compensation and the fault protection circuitry.

Compared to a discrete MOSFET and a PWM controller or

an RCCsolution, a Fairchild Power Switch(FPS) can reduce

the 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 the cost

effective design in either a flyback converter or a forward

converter

• Internal High Voltage Sense FET

• Auto-Restart Mode

Applications

• SMPS for VCR, SVR, STB, DVD & DVCD

• SMPS for Printer, Facsimile & Scanner

• Adaptor for Camcorder
