KA5L0380R 5L0380R SMPS POWER SUPLY IC

Datasheet...

Description:
The Fairchild Power Switch(FPS) product family is 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 integrates the fixed frequency oscillator, the under voltage lock-out, the leading edge
blanking, the optimized gate turn-on/turn-off driver, the thermal shutdown 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 PWM controller or an RCCsolution, a Fairchild Power Switch(FPS) can reduce the 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 the cost effective design in either a flyback converter or a forward converter.

Features:
Precision Fixed Operating Frequency (100/67/50kHz)
Low Start-up Current(Typ. 100uA)
Pulse by Pulse Current Limiting
Over Current Protection
Over Voltage Protection (Min. 25V)
Internal Thermal Shutdown Function
