TPS62065/67EVM
This user’s guide describes the characteristics, operation, and use of the TPS62065-67EVM-347
evaluation module (EVM). The TPS62065-67EVM-347 is a fully assembled and tested platform for
evaluating the performance of both the
TPS62065
and
TPS62067
2-A step-down converters. This
document includes schematic diagrams, printed circuit board (PCB) layout, bill of materials, and test data.
Throughout this document, the abbreviations EVM, TPS62065/67EVM, and the term evaluation module
are synonymous with the TPS62065-67EVM-347 unless otherwise noted.
