Fairchild Power Switch(FPS)

Features

Description

• Adjustable Switching Frequency

• Intelligent Power Saving Mode

• Pulse by Pulse Current Limiting

• Over Current Latch Protection

• Over Voltage 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

• Internal Thermal Shutdown Function

• Built-in Soft Start Function

• Internal High Voltage Sense FET

• Auto-Restart Mode

oscillator, under voltage lock out, leading edge blanking,

optimized gate turn-on/turn-off driver, thermal shut down

protection, over voltage protection, and temperature

compensated precision current sources for loop

compensation and fault protection circuitry. compared to dis-

crete 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 PC SMPS with Power Saving function.
