This reference design generates a 5V/20A output from a standard 48V telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD17312Q5, implemented as self-driven synchronous rectifiers, provide for a highly efficient design. This design is laid out in a standard 1/8th brick footprint and includes enable, remote sense, and output overvoltage features.
