KA1M0280RB/KA1H0280RB

Fairchild Power Switch(FPS)

Features

Description

• Precision Fixed Operating Frequency

• KA1M0280RB (67kHz) , KA1H0280RB (100kHz)

• Pulse by Pulse Over Current Limiting

• Over Load Protection

• Over Voltage Protection (Min. 23V)

• 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

discrete MOSFET and controller or R

switching converter

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.
