Description

The FSDM311A consists of an integrated Pulse Width Modulator (PWM) and SenseFET, and is specifically designed for high-performance, off-line, Switch-Mode Power Supplies (SMPS) with minimal external components. FSDM311A is an integrated high-voltage power switching regulator that combines a VDMOS SenseFET with a voltage-mode PWM control block. The integrated PWM controller features include a fixed oscillator, Under-Voltage Lockout (UVLO) protection, Leading-Edge Blanking (LEB), an optimized gate turn-on/turn-off driver, Thermal Shutdown (TSD) protection, and temperature-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 FSDM311A device reduces total component count and design size and weight, while increasing efficiency, productivity, and system reliability. This device provides a basic platform that is well suited for the design of cost-effective flyback converters.
