Description

This reference design generates a 12V/10A output from a standard 48V telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD18531Q5A, implemented as self-driven synchronous rectifiers, provide for a highly efficient design. This design is laid out in a standard 1/8th brick footprint and includes enable, remote sense, and output overvoltage features.

Features
  • 36V to 75VDC Input, 12V/10A Output (120W)
  • Active Clamp Foward Topology
  • Features UCC2897A Controller along with TI NexFET Synchronous Rectifiers
  • Industry Standard Eighth Brick Footprint
  • Output Overvoltage protection
  • Romote Sense
