Overview

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

Description

This reference design is a low-cost, high-density USB adapter that uses the UCC28782 active-clamp flyback controller and UCC5304 isolated driver in a ZVS-flyback topology. The maximum power rating is 65 W at 20-V output but is adjustable for 20-V/15-V/9-V/5-V output voltages and 3 A. This design reaches a peak efficiency of 93.4%. The average efficiency and standby power levels are designed to meet DoE level VI and CoC Tier 2 limits. The compact design has dimensions of 44 mm by 54 mm by 20mm (48cc open frame).

Features

  • Compact size of 44 mm by 54mm by 20 mm (48 cc open frame)
  • High efficiency, 93.4% peak
  • EMI data provided in test report, below CISPR32 limits
  • Supports variable output voltage 5 V to 20 V
  • Designed to meet efficiency and standby requirements of DoE Level VI and CoC Tier 2

Typical applications

  • Notebook PC power adapter design
