Description

This reference design uses the UCC2897A active clamp controller to generate an isolated 28V/3.6A output from a standard 24Vdc telecom input. This design uses diode rectification on the output stage and achieves efficiencies up to 93%. The output is adjustable down to 24V by changing a single resistor value.

Features
  • 18-36V Input, 28V/3.6A Output
  • Standard 24Vdc telecom input range
  • Efficiency up to 93%
  • Diode Rectification
  • Adjustable Output as low as 24V
  • Active Clamp Forward Topology, featuring UCC2897A Controller
