Texas Instruments UCC28780 | Demoboard TIDA-010047

22-W/in3, 93.1% peak efficiency, 100-W USB-PD 3.0 AC/DC adapter reference design with Si MOSFET

Overview

TopologyFlyback Converter
Input voltage100-240 V
Output 120 V / 5 A
IC revisionE1

Description

This fully-tested reference design is a high-efficiency, high-power-density, AC/DC adapter solution with a wide input voltage range (100- to 240-V AC) for laptop adapters and smartphone charger applications. This design consists of a front-end transition-mode (TM) power factor correction (PFC) circuit based on the UCC28056 device, followed by an active-clamp flyback for isolated DC/DC conversion based on the UCC28780 device.

Features

  • Relatively low-cost solution
  • Solution based on the both-ended USB Type-C® cable
  • Relatively high power density with active-clamp flyback topology
  • Meets DoE level VI and CoC Tier2 regulations
  • Robust protection built-in

Typical applications

  • Notebook PC, Mobile wall charger, AC/DC adapters, PSU
  • Industrial AC/DC
