Overview

This compact, high efficiency reference design with a 54-V DC, 1000-W output targets 5G telecom power and industrial AC/DC power supplies. The circuit consists of a front-end continuous conduction mode (CCM) power factor correction (PFC) circuit based on the UCC28180, followed by a robust LLC stage for an isolated DC/DC converter based on the UCC256403. For high efficiency needs, the UCC24624 handles synchronous rectification. This design uses an auxiliary power supply flyback with the UCC28911, which has an internal high-voltage MOSFET. This design enables 95.9% peak efficiency and allows the system to work without forced cooling. The whole system has low iTHD, with 30% load at <12%, 50% load at <8%, 100% load at <5.5%, and good load transient performance.

Features
  • Peak efficiency of 95.9% at 230-V AC and 95% across 30%~100% load
  • CCM PFC and half bridge LLC based (UCC28180 and UCC256403)
  • Low iTHD: 30% load at <12%, 50% load at <8%, 100% load at <5.5%
  • Good load transient performance at less than 1% regulation
  • Meets ±1% accuracy for input power meter across whole load range
  • Passive cooling with sealed metal case

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
