EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 3 V to 5 V and the output voltage range of

3 V to 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 85 ＝ 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.
