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
| Topology | LLC Resonant Converter |
| Input voltage | 6-26 V |
| Output 1 | -5 V / 0.09 A |
| Output 2 | 18 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.
