8V-36V Input 12V/7A; Active Clamp Forward Reference Design
PMP5123
(ACTIVE)
See the Important Notice and Disclaimer covering reference designs and other TI resources.
Description
This reference design generates an isolated 12V/7A output from an 8V to 36V DC input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD19533Q5A and CSD19534Q5A allow this design to achieve a max load efficiency over 93%, with a peak efficiency of over 94%. The compact UCC27511 drivers simplify the gate drive circuitry for the synchronous rectifiers.
Features
- High Efficiency (over 94% peak)
- Low profile, less than 0.5 inches (12.5mm) max component height
- Self-driven synchronous rectifiers reduce drive complexity
