Test Setup

4.2 Recommended Test Setup

Figure 3. TPS53310EVM-755 Recommended Test Setup

Figure 3 is the recommended test setup to evaluate the TPS53310EVM-755. When working at an ESD

workstation, make sure 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 5 A

maximum. Ensure that VIN is set initially to 0 V and connected as shown in Figure 3.

2. Connect a voltmeter V1 at TP5 (Vin_MST) and TP8 (GND) to measure input voltage.

3. Connect a current meter A1 between VIN DC source and J6.

Output Connections:

1. Connect Load1 to J3, and set Load to constant resistance mode to sink 0 Adc before Vin is applied.

2. Connect a voltmeter V2 at TP7 (Vout_MST) and TP10 (GND) to measure the 1.5-V output voltage.

3. Connect Load2 to J8, and set Load to constant resistance mode to sink 0 Adc before Vin is applied.

4. Connect a voltmeter V3 at TP19 (Vout_SLV) and TP21 (GND) to measure the 1.2-V output voltage.
