Description

This reference design generates a 5V/10A output from a standard telecom 48V DC input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD17309Q3 and CSD18540Q5B, implemented as self-driven synchronous rectifiers, allow this design to achieve a max load efficiency over 93%.  This design uses only ceramic output capacitors for high reliability and uses 100% surface mount components.  The board is laid out on a standard eighth brick footprint.

Features
  • Industry standard 1/8 Brick Footprint, 0.9" x 2.3" (23mm x 58mm)
  • High efficiency (greater than 93%)
  • All ceramic output capacitors
  • Self-driven synchronous rectifiers reduce drive complexity
  • 100% surface mount components
  • Low profile - 0.35" (9mm) maximum top side component height
