Description
- UCC2897A evaluation module (EVM) is an active clamp reset forward converter providing a 3.3-V regulated output 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. The module uses the UCC2897A Current Mode Active Clamp PWM Controller for effectively demonstrating the active clamp transformer reset technique
