DC1994A - LT3752EFE/LT8311EFE Isolated Demo Board | 18V ≤ VIN ≤ 72V; VOUT: 12V @ 12A

Demonstration circuit 1994A is an active clamp forward converter with synchronous rectification featuring the LT®3752/LT8311 chipset. 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%.
