52V-60Vdc Input, 12V/22A Active Clamp Forward
View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
This reference design generates a 12V/21.7A output from 54V DC input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD18531Q5A, implemented as self-driven synchronous rectifiers, allow this design to achieve a max load efficiency of nearly 95%.
