5.2 Recommended Test Setup
is the recommended test set up to evaluate the TPS53313EVM-078. 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 5-2. TPS53313EVM-078 Recommended Test Set Up
5.2.1 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
• Connect a current meter A1 between VIN and J2 to measure the input current.
• Connect a voltmeter V1 at TP3 (VIN) and TP6 (GND) to measure the input voltage.
5.2.2 Output Connections
• Connect Load to J5 and set load to constant resistance mode to sink 0 A
DC
before VIN is applied.
• Connect a voltmeter V2 at TP10 (VOUT) and TP8 (GND) to measure the output voltage.
5.2.3 Other Connections
• Place a fan as shown in
and turn on, making sure air is flowing across the EVM.
