Operation
This chapter describes the TPA3139D2EVM board in regards to power supply and system interfaces. The
chapter provides information about handling and unpacking, absolute operating conditions, and a
description of the factory default switch and jumper configuration.
The following sections provide a step-by-step guide to configuring the TPA3139D2EVM for device
evaluation.
2.1
Electrostatic Discharge Warning
Many of the components on the TPA3139D2EVM are susceptible to damage by electrostatic discharge
(ESD). Customers are advised to observe proper ESD handling precautions when unpacking and handling
the EVM, including the use of a grounded wrist strap at an approved ESD workstation.
CAUTION
Failure to observe ESD handling procedures may result in damage to EVM
components.
2.2
Unpacking the EVM
When opening the TPA3139D2EVM package, ensure that the following item is included:
•
A 1-piece TPA3139D2EVM board using one TPA3139D2
If either of these items is missing, contact the TI Product Information Center nearest you to inquire about a
replacement.
2.3
Power Supply Setup
A power supply is required to power up the EVM. Because most of the pins are PVCC compliant, the
PVCC supply can also be used to power the analog supply (AVCC) and can be used to pull up the logic
pins for shutdown (SD) control, and fault detection (FAULT).

EVM Preparations
Complete the following steps to prepare the EVM for use:
1. Ensure that the external power source is set to OFF.
2. Connect the external regulated power supply adjusted from 3.5 V to 14.4 V to the module PVCC and
GND banana jacks, taking care to observe marked polarity.
