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. This device 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
count, size, and weight, while simultaneously increasing
efficiency, productivity, and system reliability. This device is a
basic platform which is well suited for cost effective designs
of flyback converters.
