Recommended Test Setup
Figure 4. TPS51727EVM Recommended Test Setup
is the recommended test setup to evaluate the TPS51727EVM. Working at an ESD workstation,
ensure that any wrist straps, bootstraps, or mats are connected, referencing the user to earth ground
before power is applied to the EVM.
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 15 A
maximum. Ensure that Vin is initially set to 0 V and connected as shown in
.
2. Connect a voltmeter V1 at TP5 (Vin) and TP6 (GND) to measure the input voltage.
Output Connections:
1. Connect Load to J3 and J4, and set Load to constant resistance mode to sink 0 Adc before Vin is
applied.
2. Connect a voltmeter V2 at TP7(Vout) and TP8 (GND) to measure the output voltage.
Other Connections:
Place a fan as shown in
and turn it on, ensuring that air is flowing across the EVM.
