Description
The FSGM0765R is an integrated Pulse Width
Modulation (PWM) controller and SenseFET specifically
designed for offline Switch-Mode Power Supplies
(SMPS) with minimal external components. The PWM
controller includes an integrated fixed-frequency
oscillator, Under-Voltage Lockout (UVLO), Leading-
Edge Blanking (LEB), optimized gate driver, internal
soft-start, temperature-compensated precise current
sources for loop compensation, and self-protection
circuitry. Compared with a discrete MOSFET and PWM
controller solution, the FSGM series can reduce total
cost, component count, size, and weight; while
simultaneously increasing efficiency, productivity, and
system reliability. This device provides a basic platform
suited for cost-effective design of a flyback converter.
