Texas Instruments UCC25800 | Demoboard UCC25800EVM-1

UCC25800 evaluation module for 2-W LLC converter with 6-V to 26-V DC input and 18-V and 5-V outputs

Overview

TopologyLLC Resonant Converter
Input voltage6-26 V
Output 1-5 V / 0.09 A
Output 218 V / 0.09 A

Description

This isolated open-loop LLC transformer driver converter is based on the device UCC25800 and has a pair of outputs, +18-V and -5-V, and provides output power up to 2 W from 6-V to 26-V DC input to provide isolated bias power to SiC MOSFET or IGBT gate drivers for traction inverter and industrial inverter applications. The LLC topology allows the transformer to have significant leakage inductance, but much smaller primary-to-secondary capacitance, which significantly reduces common-mode current injection through the bias transformer. The LLC converter based on UCC25800 offers a high level of integration, low cost and high efficiency in a compact form factor.

Features

  • UCC25800 2-W LLC converter with 6-V to 26-V dc input and 18-V and 5-V outputs
  • Provide isolated bias power to SiC MOSFET or IGBT gate drivers for traction inverter and industry inverter applications
  • Allow transformer with significant leakage inductance but much less primary-to secondary capacitance to reduce common-mode current injection
  • Offer a high level of integration, low cost and high efficiency in a compact form factor

Typical applications

  • UPS
  • Industrial motors, elevators and escalators
  • solar inverter
  • EV charging station, DC fast charging station, Automotive DC/DC converter, Automotive traction inverter & motor control, Automotive on-board charger (OBC)
