Description
- UCC2891EVM-520, Evaluation Board Using the UCC2891 Active-Clamp Current-Mode PWM Controller. The UCC2891EVM-520 evaluation module (EVM) is a forward converter providing a 3.3-V regulated output at 30 A of load current, operating from a 48-V input. The EVM operates over the full 36-V to 75-V telecom-input range, and is able to fully regulate down to zero-load current. The module uses the UCC2891 current-mode active-clamp PWM controller for effectively demonstrating the active-clamp transformer-reset technique
