Abstract

This user’s guide provides a description as well as directions for use of the UCC14240EVM-052 to evaluate the UCC14240-Q1, high frequency, integrated transformer, DC-DC converter module from Texas Instruments. This EVM allows designers to quickly and efficiently evaluate the UCC14240-Q1 for use in automotive or industrial applications requiring gate driver IC bias power as high as 2-W, meeting up to 3-kVRMS isolation.
