It is important to operate this EVM within the input and output voltage ranges as specified in the table provided
below.
Input Range, V
S+
to V
S–
3.0 V to 6.0 V
Input Range, V
I
3.0 V to 6.0 V NOT TO EXCEED VS+ or VS–
Output Range, V
O
3.0 V to 6.0 V NOT TO EXCEED VS+ or VS–
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 product data sheet or EVM user's guide (if user's guide is
available) 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 30 ° C. The EVM is
designed to operate properly with certain components above 50 ° 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 material provided. When placing measurement probes near these devices during operation, please
be aware that these devices may be very warm to the touch.
