This User's Guide describes the characteristics, operation, and use of the TPS61280 evaluation module
(EVM). This EVM enables test and evaluation of the Texas Instruments'
(typ.), up to 4.8-V input, step-up dc-dc converter with integrated Pass-Through Mode. This User's Guide
includes EVM specifications, user software description, the schematic diagram, bill of materials, and board
layout. After the release of the A-version device in the summer of 2014, the EVM is assembled with the
TPS61280A (supports PWM mode during startup which is not available for TPS61280).
