WARNINGS RESTRICTIONS important operate this within input voltage range output voltage range Exceeding specified input range cause unexpected operation and/or irreversible damage EVM. there questions concerning input range, please contact field representative prior connecting input power. Applying loads outside specified output range result unintended operation and/or possible permanent damage EVM. Please consult User's Guide prior connecting load output. there uncertainty load specification, please contact field representative. During normal operation, some circuit components have case temperatures greater than 55°C. designed operate properly with certain components above 55°C long input output ranges maintained. These components include limited linear regulators, switching transistors, pass transistors, current sense resistors. These types devices identified using schematic located User's Guide. When placing measurement probes near these devices during operation, please aware that these devices very warm touch. Mailing Address: Texas Instruments Post Office 655303 Dallas, Texas 75265
