Description

This reference design is a gallium nitride (GaN) based, 140W AC-DC power with high effciency and power density. It supports wide input (90VAC to 264VAC) and output (5V to 28V) voltages. It is designed for the application, such as the adaptor design for USB PD3.1 and the charger for power tools.

Features

  • Wide output power range from 5V to 28V for USB PD3.1 application
  • PFC is designed by TI 120mΩ single GaN with driver integrated and UCC28056 transition mode (TM) PFC controller
  • AHB is designed by TI half bridge GaN as 170mΩ/248mΩ GaN device with driver, level shift and bootstrap diode integrated

  • 94% efficiency at 115VAC input and >95.5% efficiency at 230VAC input

  • High power density design: 27.33W/in³ with the PCB size: 50mm × 73mm × 23mm

Typical applications

  • Mobile wall charger design, Merchant battery charger
  • Notebook PC power adapter design, Other AC/DC adapters and PSU
