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.
