† See the Texas Instruments document, PowerPAD Thermally Enhanced Package Application

Report (literature number SLMA002), for more information on the PowerPAD package. The

thermal data was measured on a PCB layout based on the information in the section entitled Texas

Instruments Recommended Board for PowerPAD

 of the before mentioned document. Data in

table is for specified layout. Under other conditions the thermal performance may vary. See Texas

Instruments document SLAA117 for more detailed application information.
