| Input voltage | 90-264 V |
| Output 1 | 20 V / 3.25 A |
| IC revision | B |
Description
The UCC28782EVM-030 is a 65-W USB-C PD evaluation module (EVM) for evaluating an off-line active-clamp flyback adapter for notebook charging and other applications. The EVM meets CoC Tier 2 and DoE Level 6 efficiency requirements. It is intended for evaluation purposes and is not intended to be an end product. The UCC28782EVM-030 converts input voltage of 90-VRMS to 264-VRMS down to USB-C PD selectable output voltage 20-VDC, with a max 3.25-A, and to 5-VDC, 9-VDC, and 15-VDC, with a max 3.00-A output current rating and a 160-ms limit for over-power capability. The main devices used in this design are active clamp flyback controller UCC28782 and GaN MOSFETs. Please read this user's guide thoroughly before applying power to this board.
