240W USB PD AC/DC 适配器

概览

该电源设计提供强劲的 240W 输出，符合 USB PD 3.2 EPR 标准。 它可满足不同的电源要求，并符合欧洲有关便携式设备使用 USB Type-C 通用充电器的规定。

系统优势：

  • 根据 USB 规格提供最大功率（48V/5A），确保为高要求设备提供可靠且稳定的电源。
  • 零电压开关（ZVS）最大限度地减少了开关损耗，从而实现高效率（28V 5A 时 >94%）。
  • 已加强的功率密度减小了尺寸和减轻了重量，同时让热管理得以改进。

This video demonstrates Renesas’ 240W USB Power Delivery (USB PD) AC/DC adapter design, featuring advanced SuperGaN FETs and innovative controllers for high efficiency, compact size, and USB PD 3.2 compliance. The two-stage architecture, PFC and ZVS flyback, ensures optimal power factor correction and minimal switching losses. The design delivers 48V/5A with over 96% efficiency at full load, while normally-off depletion-mode GaN FETs reduce losses, improve thermals, and enable a smaller footprint for next-generation power adapters.
