5.2 Recommended Test Setup
Figure 3 is the recommended test set up to evaluate the TPS53316EVM-075. 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.
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. Make sure VIN is initially set to 0 V and connected to J2 as shown in Figure 3 .
2. Connect a current meter A1 between VIN and J2 to measure the input current.
3. Connect a voltmeter V1 at TP6 (VIN) and TP9 (GND) to measure the input voltage.
Output Connections:
1. Connect Load to J3 and set Load to constant resistance mode to sink 0 A
DC
before VIN is applied.
2. Connect a voltmeter V2 at TP7 (VOUT) and TP10 (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.
