Fairchild Power Switch(FPS)

Features

Description

• Quasi Resonant Converter Controller

• Internal Burst Mode Controller for Stand-by Mode

• Pulse by Pulse Current Limiting

• Over Current Latch Protection

• Over Voltage Protection (Vsync: Min. 11V)

• 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) consist of high

voltage power SenseFET and current mode PWM controller IC.

PWM controller features integrated fixed 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

• Internal High Voltage Sense FET

• Auto-Restart Mode

discrete MOSFET and controller or R

switching converter

solution, a 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 design in quasi

resonant converter as C-TV power supply.
