4.2 Recommended Test Setup

Figure 4. TPS51513EVM-549 Recommended Test Set Up

Figure 4 is the recommended test set up 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. 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, and turn it on, ensuring that air is flowing across the EVM.

5 Configuration

All jumper selections must be made prior to applying power to the EVM. Users can configure this EVM

with the following configurations.
