KA5H0165R/RN, KA5M0165R/RN, KA5L0165R/RN,

KA5H0165RVN

Fairchild Power Switch(FPS)

Features

Description

• Precision Fixed Operating Frequency (100/67/50kHz )

• Low Start-up Current (Typ. 100uA)

• Pulse by Pulse Current Limiting

• Over Load Protection

• Over Voltage Protection (Min. 25V)

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 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

- except KA5H0165RVN

• Internal Thermal Shutdown Function

• Under Voltage Lockout

• Internal High Voltage Sense FET

• Auto-Restart Mode

compared to discrete MOSFET and controller or R

switching converter solution, The Fairchild Power Switch(FPS)

can reduce total component count, design size, weight and at the

same time increase efficiency, productivity, and system

reliability. It is well suited for cost effective design of flyback

converters.
