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

switching 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.
