Fairchild Power Switch(FPS)

Features

Description

• Wide Operating Frequency Range Up to 150Khz

• Lowest Cost SMPS Solution

• Lowest External Components

• Low Start up Current (Max:170uA)

• Low Operating Current (Max:15mA)

• Internal High Voltage SenseFET

The Fairchild Power Switch(FPS) product family are

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 features the

integrated fixed oscillator, the under voltage lockout, the

optimized gate turn on/turn off driver, the thermal shut

down 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 controller or a RCC

switching converter solution, a Fairchild Power Switch(FPS)

can reduce the total component count, design size, and

weight and at the same time increase efficiency,

• Built-in Auto Restart Circuit

• Over Voltage Protection (Auto Restart Mode)

• Over Load Protection (Auto Restart Mode)

• Over Current Protection (Auto Restart Mode)

• Internal Thermal Protection(Auto Restart Mode)

• Pulse By Pulse Over Current Limiting

• Internal Burst Mode Controller for Stand-by Mode

• Under Voltage Lockout With Hysteresis

• External Sync. Terminal

productivity, and system reliability. It has a basic platform

well suited for the cost effective monitor power supply.
