This reference design generates a 3.3V/12A output from a wide 18V-60V telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD17501Q5A and CSD18502Q5B, implemented as self-driven synchronous rectifiers, provide for an efficient design. This design is laid out in a standard quarter brick footprint and includes enable, positive rail remote sense, and output trimming features.
