Description

This reference design generates a 1.2V/25A output from a standard 48V telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate thresholds of the CSD16401Q5 and CSD16325Q5 allow these devices to be used as self-driven synchronous rectifiers for a highly efficient design. This design also includes enable, remote sense, and output overvoltage features.
