Description

The FSD200 and FSD210 are integrated Pulse Width Modu-lators (PWM) and Sense FETs specially designed for high performance off-line Switch Mode Power Supplies (SMPS) with minimal externalcomponents. Both devices are mono- lithic high voltage power switching regulators which com- bine an LDMOS Sense FET with a voltage mode PWM control block. The integrated PWM controller features of FSD200 and FSD210 in clude: a fixed oscillator with frequency modulation for reduced EMI, Under Voltage Lock Out (UVLO) protection, Leading Edge Blanking (LEB), optimized gate turn-on/turn- off driver, thermal shut down protection (TSD), temperature compensated precision current sources for loop compensa- tion and fault protection circuitry. When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSD200 and FSD210 reduce total component count, design size, weight and at the same time increase effi- ciency, productivity, and system reliability. The FSD200 eliminates the need for an auxiliary bias winding at a small cost of increased supply power. Both devices are a basic platform well suited for cost effective designs of flyback converters.
