5.2 Recommended Test Setup

Figure 5-2 is the recommended test setup to evaluate the TPS53014EVM-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.

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 5-2.
  • 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 ADC 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 5-2 and turn on, making sure air is flowing across the EVM.
