DC1994A, Demonstration Board using LT3752EFE Active Clamp forward Converter with Synchronous Rectification. This circuit was designed to demonstrate the high levels of performance, efficiency, and small solution size attainable using these parts. It operates at 240kHz and produces a regulated 12V, 12A output from an input voltage range of 18 to 72V, suitable for telecom, industrial, and other applications. It has an eighth-brick footprint area. Synchronous rectification helps to attain efficiency exceeding 94%. The DC1994 circuit features soft-start which prevents output voltage overshoot on startup or when recovering from overload condition
