240W USB PD AC/DC Adapter

Overview

This power supply design delivers a robust 240W output, compliant with the USB Power Delivery (PD) 3.2 Extended Power Range (EPR) standard. It caters to diverse power supply requirements and adheres to European regulations mandating the use of USB Type-C universal chargers for various portable electronic devices.

System Benefits:

  • Delivers maximum power per USB specifications (48V/5A), ensuring reliable and consistent power for high-demand devices.
  • Zero voltage switching (ZVS) minimizes switching loss for high efficiency (>94% at 28V, 5A).
  • Enhanced power density reduces size and weight while achieving improved thermal management.

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.
