Using the UCC14131EVM-070 for Biasing GaN and Gate
Driver ICs in Automotive and Industrial Applications
This user's guide provides a description and instructions for use of the UCC14131EVM-070 to evaluate the
UCC14131-Q1; a high frequency, integrated transformer, DC-DC converter module from Texas Instruments. This
EVM allows designers to quickly and efficiently evaluate the UCC14131-Q1 for use in automotive or industrial
applications requiring gate driver IC bias power as high as 1.5 W, meeting up to 5 kV
