EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 0 V to 4 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
100

°

C. The EVM is designed to operate properly with certain components above 100

°

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.
