may not be complete in terms of design and/or manufacturing related protective considerations including product safety measures
typically found in the end-product incorporating the module. As a prototype, this product does not fall within the scope of the
European Union Directive on electromagnetic compatibility and on low voltage and therefore may not meet the technical
requirements of the directive. This EVM is not subject to the EU marking requirements.

Should this EVM not meet the specifications indicated in the User’s Guide the EVM may be returned within 30 days
from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY
TI AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING ANY
WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.

The user assumes all responsibility and liability for proper and safe handling of the EVM. The user acknowledge that the use
of the EVM could present serious hazards and that it is the user’s responsibility to take all precautions for the handling and
use of the EVMs in accordance with good laboratory practices. Please be aware that the products received may not be
regulatory compliant or agency certified (FCC, UL, etc.). Due to the open construction of the product, it is the user’s
responsibility to take any and all appropriate precautions with regard to electrostatic discharge.

NEITHER PARTY WILL BE LIABLE TO THE OTHER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
CONSEQUENTIAL DAMAGES.

TI is currently dealing with various customers for products, and therefore our arrangement with the user will not be
exclusive
.

TI assumes no liability for applications assistance, customer product design, software performance, or infringement
of patents or services described herein
.

Please read the User’s Guide and specifically the section in the User’s Guide pertaining to warnings and restrictions prior to
handling the product. This section contains important information regarding high temperature and voltages which TI
recommends to be read before handling the EVMs. In case of any doubt regarding safety, please contact the TI application
engineer.

Persons handling the product should have electronics training and observe good laboratory practice standards.

No license is granted under any patent right or other intellectual property right of TI covering or relating to any combination,
machine, or process in which such TI products or services might be or are used.

This Agreement is subject to the laws of the State of Texas, excluding the body of conflicts of laws and the United Nations
Convention on the International Sale of Goods, and will be subject to the exclusive jurisdiction of the courts of the State of
Texas.

EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 2.6 V to 4.5 V and the output voltage range of 2.6 V to 4.5 V.

Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are
questions concerning the input range, please contact a TI field representative prior to connecting the input power.

Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.

During normal operation, some circuit components may have case temperatures greater than 25

°

C. The EVM is designed to

operate properly with certain components above 70

°

C as long as the input and output ranges are maintained. These components

include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.
