This reference design generates a 12V/13A output from 54V DC input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD18532Q5B, implemented as self-driven synchronous rectifiers, allow this design to achieve a max load efficiency over 95%. The compact UCC27511 drivers simplify the gate drive circuitry for the synchronous rectifiers.
- High Efficiency (over 95%)
- Generates regulated 12V bus for telecom or server applications
- Low profile, less than 0.5 inches (12.5mm) max component height
- Self-driven synchronous rectifiers reduce drive complexity
