KA1M0265R/KA1H0265R

Fairchild Power Switch(FPS)

Features

Description

• Precision Fixed Operating Frequency

• KA1M0265R (70kHz) , KA1H0265R (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 discrete MOSFET and

• Internal High Voltage Sense FET

• Auto Restart

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.
