3.1 Output Voltage Setpoint
To change the output voltage of the EVMs, it is necessary to change the value of resistor R
4
. Changing the
value of R
4
can change the output voltage. The value of R
4
for a specific output voltage can be calculated using
Equation 1 .

4 Test Setup and Results
This section describes how to properly connect, set up, and use the TPS62933EVM. The section also includes
test results typical for the evaluation modules and efficiency, output load regulation, output line regulation, load
transient response, output voltage ripple, input voltage ripple, start-up, and shut-down.
4.1 Input/Output Connections
The TPS62933EVM is provided with input/output connectors and test points as shown in Table 4-1 . Figure 4-1
shows connectors and jumpers placement on TPS62933EVM board.
A power supply capable of supplying 3-A must be connected to J2 through a pair of 20-AWG wires. The load
must be connected to J1 through a pair of 20-AWG wires. The maximum load current capability is 3-A. Wire
lengths must be minimized to reduce losses in the wires. Test point TP3 provides a place to monitor the V
IN
input
voltages with TP7 providing a convenient ground reference. TP1 is used to monitor the output voltage with TP9
as the ground reference.
