Description

The FSDM101 is an integrated Pulse Width Modulator(PWM) and Sense FET specially designed for high performance offline Switch Mode Power Supplies (SMPS) with minimal external components. FSDM101 is a monolithic high voltage power switching regulator which combines a VDMOS Sense FET with a voltage mode PWM control block. The integrated PWM controller features include: a fixed oscillator, Under Voltage Lock Out (UVLO) protection, Leading Edge Blanking (LEB), optimized gate turn-on/ turn-off driver, thermal shut down protection (TSD), temper-ature compensated precision current sources for loop compensation and fault protection circuitry. When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSDM101 reduces total component count, design size, weight and at the same time increases efficiency, productivity, and system reliability. This device is a basic platform well suited for cost effective designs of flyback converters.
