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 TPS2458EVM and test equipment as shown in Figure 2 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 Table 3 .

Note: Run separate leads from the GND jacks back to a common return point made near the

power supply output terminals.
