5.2 Recommended Test Setup

Figure 3 is the recommended test set up to evaluate the TPS53015EVM-126. Working at an ESD

workstation, make sure that any wrist straps, bootstraps or mats are connected referencing the user to

earth ground before power is applied to the EVM.

Figure 3. TPS53015EVM-126 Recommended Test Set Up

Input Connections:

• Prior to connecting the DC input source VIN, it is advisable to limit the source current from VIN to 2 A

maximum. Make sure VIN is initially set to 0 V and connected to J2 as shown in Figure 3.

• Connect a current meter A1 between VIN and J1 to measure the input current.

• Connect a voltmeter V1 at TP1 (VIN) and TP2 (GND) to measure the input voltage.

Output Connections:

• Connect Load to J2 and set load to constant resistance mode to sink 0 A

before VIN is applied.

• Connect a voltmeter V2 at TP7 (VOUT) and TP8 (GND) to measure the output voltage.

Other Connections: Place a fan as shown in Figure 3 and turn on, making sure air is flowing across the

EVM.
