30-W/in3, 94% Efficiency, 65-W USB Type-C PD AC/DC Adapter Reference Design

Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 120 V / 3.25 A
IC revisionA

Description

This fully tested, USB power delivery reference design is a high efficiency, high power density, AC/DC adapter solution with a wide input voltage range (85 - 265VAC) for laptop adapters and smartphone charger applications. It adopts active-clamp-flyback topology controlled by TI’s newest ACF controller UCC28780 as the mainly power supply stage. This design uses TPS25740B, TI’s PD source controller, to achieve a full PD 2.0 function. The design achieves a peak efficiency of 92% at a very high switching frequency. The design’s power density is increased to 30 W/in³, which is much higher than traditional solutions.

Features

  • High efficiency (92% peak value)
  • High power density (30W/in³)
  • Low no load power consumption (60mW)
  • Low light load input power (0.5W), @20Vout/0.25W output
  • Fully compatible with USB PD 2.0 standard, with 5V/3A, 9V/3A, 15V/3A, 20V/3.25A output
  • Active-clamp flyback + SR topology
  • Small size (62mm26.8mm20mm)

Typical applications

  • Smart phone, Laptop
  • Industrial AC/DC
