EVALUATION BOARD/KIT IMPORTANT NOTICE

Texas Instruments (TI) provides the enclosed product(s) under the following conditions:

This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR
EVALUATION PURPOSES ONLY
 and is not considered by TI to be a finished end−product fit for general consumer use.
Persons handling the product(s) must have electronics training and observe good engineering practice standards. As
such, the goods being provided are not intended to be complete in terms of required design−, marketing−, and/or
manufacturing−related protective considerations, including product safety and environmental measures typically found
in end products that incorporate such semiconductor components or circuit boards. This evaluation board/kit does not
fall within the scope of the European Union directives regarding electromagnetic compatibility, restricted substances
(RoHS), recycling (WEEE), FCC, CE or UL, and therefore may not meet the technical requirements of these directives
or other related directives.

Should this evaluation board/kit not meet the specifications indicated in the User’s Guide, the board/kit may be returned
within 30 days from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE
WARRANTY MADE BY SELLER TO BUYER 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 goods. Further, the user indemnifies
TI from all claims arising from the handling or use of the goods. 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.

EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE
OTHER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.

TI currently deals with a variety of customers for products, and therefore our arrangement with the user  is not  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 Warnings and Restrictions notice in the User’s Guide prior to handling
the product. This notice contains important safety information about temperatures and voltages. For additional information
on TI’s environmental and/or safety programs, please contact the TI application engineer or visit www.ti.com/esh.

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

FCC WARNING

This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR
EVALUATION PURPOSES ONLY
 and is not considered by TI to be a finished end−product fit for general consumer use.
It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of
computing devices pursuant to part 15 of FCC rules, which are designed to provide reasonable protection against radio
frequency interference. Operation of this equipment in other environments may cause interference with radio
communications, in which case the user at his own expense will be required to take whatever measures may be required
to correct this interference.

EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 1.8VDC to 5 VDC; and the output voltage range of
1.8 VDC to 5 VDC.

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.

During normal operation, some circuit components may have case temperatures greater than 30

°

C The EVM is designed

to operate properly with certain components above 85

°

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.
