Product Summary

The 5L0265R is a Fairchild Power Switch(FPS) specially designed for an off-line SMPS with minimal external components. The 5L0265R consists 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 currentsources for loop compensation and fault protection circuitry-compared to discrete MOSFET and controller or RCC switching converter solution.
