Product Summary

The 5L0165R is a Fairchild Power Switch(FPS) which 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 compared to discrete MOSFET and controller or RCC switching converter solution, The 5L0165R can reduce total component count, design size, weight and at the same time increase efficiency, productivity, and system reliability. The 5L0165R is well suited for cost effective design of flyback converters.
