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

switching 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.
