PMP9108, 36V-75Vdc Input, 5V/50W 1/8 Brick Active Clamp forward Reference Design

PMP9108, 36V-75Vdc Input, 5V/50W 1/8 Brick Active Clamp forward Reference Design. This reference design generates a 5V/10A output from a standard telecom 48V DC input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD17309Q3 and CSD18540Q5B, implemented as self-driven synchronous rectifiers, allow this design to achieve a max load efficiency over 93%. This design uses only ceramic output capacitors for high reliability and uses 100% surface mount components
