Description

This reference design generates an isolated 5V/100W output from a high voltage DC input. This design is intended to operate from the output of a PFC front end regulator. The UCC2897A is used to control an active clamp forward converter. Self-driven synchronous rectifiers allow for 91% efficiency. An accurate current limit is provided by directly sensing the output current. A clock pulse output is also provided for synchronizing with other converters.

Features
  • 220V-400VDC to 5V/20A Output (100W)
  • 91% efficiency
  • Ouput Current Sensing
  • Features UCC2897A Controller along with TI NexFET Synchronous Rectifiers
  • Active Clamp Forward Topology
  • Reduced conduction losses and die area of the synchronous rectifiers
