Description

The FSDH0165 is specially designed for an off-line SMPS with minimal external components. The FSDH0165 is a monolithic high voltage power switching regulator that combine the SenseFET(LDMOS) with voltage mode PWM control block.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 and temperature compensated precision current sources for loop compensation and fault protection circuitry. compared to discrete MOSFET and controller or R_CCswitching converter solution, a FSDH0165 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.
