This reference design generates a 12V/10A output from a wide range 18V to 72V telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD18533Q5A, implemented as a synchronous rectifier, provides for a highly efficient design. This design is laid out in a standard quarter brick footprint and achieves efficiencies near 95%.
- High efficiency ~95% peak
- Footprint compatible with standard 1/4 brick
- Self-driven synchronous rectifiers reduce drive complexity
- Lower cost solution compared to modules
