Figure 4-2 is the recommended test setup to evaluate the TPS51513EVM-549. Working at an ESD workstation, ensure that any wrist straps, bootstraps, or mats are connected, referencing the user to earth ground before handling the EVM.

Input Connections:

  1. Prior to connecting the dc input source, VIN, it is advisable to limit the source current from VIN to 10 A maximum. Ensure that VIN is initially set to 0 V as shown in Figure 4-2.
  2. Connect a voltmeter V1 at TP1 (VIN) and TP2 (GND) to measure the input voltage.
  3. Connect a current meter A1 between VIN DC source and J1.

Output Connections

  1. Connect Load to J2, J3, and set Load to constant resistance mode to sink 0 ADC before VIN is applied.
  2. Connect a voltmeter V2 at TP5 (VOUT) and TP8 (GND) to measure the output voltage.

Other Connections:

Place a fan as shown in Figure 4-2, and turn it on, ensuring that air is flowing across the EVM.
