9.1.1.3 EVM Warnings and Restrictions

This EVM must be operated within the input and output voltage ranges as specified in the following table.

Table 9-2 Input and Output Voltage Ranges
INPUT RANGE, VS+ TO VS– 10V TO 30V
Input range, VI 10V to 30V NOT TO EXCEED VS+ or VS–
Output range, VO 10V to 30V NOT TO EXCEED VS+ or VS–
CAUTION:

Exceeding the specified input range can cause unexpected operation, irreversible damage to the EVM, or both. If there are questions concerning the input range, contact a TI field representative before connecting the input power.

Applying loads outside of the specified output range can result in unintended operation, possible permanent damage to the EVM, or both. Consult the product data sheet or EVM user's guide (if available) before connecting any load to the EVM output. If there is uncertainty as to the load specification, contact a TI field representative.

During normal operation, some circuit components can 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, be aware that these devices can be very warm to the touch.
