Connect the TPS2458EVM and test equipment as shown in
for functional check-out of the board
and a good starting point for user evaluation of device operation. Screen print labeling on the board
employs a naming convention in keeping with the nomenclature of the target ATCA™ and MicroTCA™
applications. Input 3.3-V supply is connected to the 3V3IN jack, and the 12-V supply is connected to the
12VIN jack. A cross-reference of power rail labeling to standards naming is shown in
