TPS54336AEVM-010 3-A Regulator Evaluation Module
2 Test Setup and Results
This section describes how to properly connect, set up, and use the TPS54336AEVM-010 evaluation
module. The section also includes test results typical for the evaluation module and covers efficiency,
output voltage regulation, load transients, loop response, output ripple, input ripple, and start-up.
2.1 Input/Output Connections
The TPS54336AEVM-010 is provided with input/output connectors and test points as shown in Table 4 . A
power supply capable of supplying 2 A must be connected to J1 through a pair of 20-AWG wires. The load
must be connected to J4 through a pair of 20-AWG wires. The maximum load current capability must be
at least 4 A to use the full capability of this EVM. Wire lengths must be minimized to reduce losses in the
wires. Test-point TP1 provides a place to monitor the V
IN
input voltages with TP2 providing a convenient
ground reference. TP6 is used to monitor the output voltage with TP7 as the ground reference.
