KA5l0380RYDTU Datasheet

Power Switch


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 RCC solution, 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 KA5l0380RYDTU Features • Precision Fixed Operating Frequency (100/67/50kHz)• Low Start-up Current(Typ. lOOuA)• Pulse by Pulse Current Limiting• Over Current Protection• Over Voltage Protection (Min. 25V)• Internal Thermal Shutdown Function• Under Voltage Lockout• Internal High Voltage Sense FET• Auto-Restart Mode KA5l0380RYDTU Applications • SMPS for VCR, SVR, STB, DVD & DVCD• SMPS for Printer, Facsimile & Scanner• Adaptor for Camcorder
