Using the UCC2897AEVM

The UCC2897A evaluation module (EVM) is an active clamp reset forward converter providing a 3.3-V regulated out put at 30 A of load current, operating from a 48-V input. The design operates over the full 36-V to 72-V telecom input range, and is able to fully regulate down to zero load current. Themodule uses the UCC2897A Current Mode Active Clamp PWM Controller for effectively demonstrating the active clamp transformer reset technique.
