Test Set Up
Shown in Figure 2 is the basic test set up recommended to evaluate the TPS40131EVM.
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. Electrostatic (ESD) smock and
safety glasses should also be worn.
1. Prior to connecting the DC input source, V
IN1
, it is advisable to limit the source current from V
IN1
to 10A
maximum. Make sure V
IN1
is initially set to 0V and connected as shown in Figure 2 .
2. Connect V
IN2
to J2 and set V
IN2
to 5V.
1. Connect LOAD to J4 and J5, set LOAD to constant current mode to sink 0A DC before V
IN1
is applied.
2. Connect voltmeter, V2, across TP7 and TP8, as shown in Figure 2 .
1. Place Fan as shown in Figure 2 and turn on, making sure air is flowing across the EVM.
