Description

The FSDH0165D is specially designed for an off-line SMPS with minimal external components. The FSDH0165D is a monolithic high voltage power switching regulator that com-bine the SenseFET(LDMOS) with voltage mode PWM control block. Included PWM controller features integrated fixed oscil-lator, under voltage lock out, leading edge blanking, optimized gate turn-on/turn-off driver, thermal shutdown protection and temperature compensated precision current sources for loop compensation and fault protection circuitry. compared to discrete MOSFET and controller or R_CCswitching converter solution, the FSDH0165D can reduce total component count,design size, weight and at the same time increase efficiency,productivity, and system reliability. It has a basic platform well suited for cost effective design in a flyback converter.
