Description

The PMP20742 reference design provides 12V at 5A (60W) from a 36V-60Vdc input with over 94% efficiency. This design uses the UCC2897A active clamp controller along with synchronous rectifiers to achieve very high efficiency.  Typical applications include Power Over Ethernet, Telecom, and Server systems.

Features
  • High efficiency, over 94%
  • Low profile, 11.43 mm (0.45") maximum height
  • Self-driven synchronous rectifiers reduce cost and complexity
