Abstract

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. The EVM comes with UCC14131-Q1 populated by default but can also accommodate UCC14130-Q1. UCC14131-Q1 and UCC14130-Q1 are pin-to-pin compatible and functionally equivalent. All performance data and waveforms shown within this document were obtained testing the UCC14131-Q1 used in HVP070, Rev E1. 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 kVRMS isolation.

This user's guide can accompany UCC14131EVM-070, HVP070, Rev E1 and Rev A. Rev E1 and Rev A are identical.
