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.
