Description

The FSDM1265RB is an integrated Pulse-Width Modulator (PWM) and a SenseFET which is specifically designed for  high performance offline SMPS with minimal external  components. FSDM1265RB is an integrated high-voltage power  switching regulator which combines a rugged avalanche  Sense FET with a current mode PWM control block. The  PWM controller includes integrated fixed frequency oscillator, under-voltage lockout, leading edge blanking (LEB), optimized  gate driver, internal soft-start, and precise current sources that  are temperature compensated for loop compensation and self  protection circuitry. Compared with discrete MOSFET and  PWM controller solution, it can reduce total cost, component  ount, size, and weight, while simultaneously increasing  efficiency, productivity, and system reliability. FSDM1265RB is a  basic platform which is well suited for cost effective designs  of flyback converters.
