Test Set-Up
The following test and interface equipment (not supplied) is required to verify EVM module operation, and
begin using the EVM.
•
Power supply, 3.3 VDC, 500 mA minimum
•
Power supply, 15 VDC, 10 A minimum
•
Digital multimeters
•
Oscilloscope, 4 channel, with current probe
Connect the TPS2358EVM 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 supplies are connected to the 3V3INx jacks, and 12-V supplies are connected to
the 12VINx jacks. A cross-reference of power rail labeling to standards naming is shown in
Table 4. TPS2358EVM Output Net and Jack Naming

(1)
The 3V3INx jacks can be jumpered together with a short test lead at the board, fed from a single lead from
the power supply.
(2)
Run separate leads from the GND jacks back to a common return point made near the power supply output
terminals.
