Beschreibung
This reference design generates a 12V/16A output from a standard 48V DC telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD19533Q51, implemented as self-driven synchronous rectifiers, allow this design to achieve a peak efficiency of 95%. The compact UCC27511 drivers simplify the gate drive circuitry for the synchronous rectifiers.
Eigenschaften
- High Efficiency (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
