THERMAL INFORMATION
The PWP 14 pin package incorporates an exposed PowerPAD and the QFN 16 pin package incorporates a
similar exposed thermal pad. These exposed thermal pads are designed to be connected to an external heatsink.
The thermal pad must be soldered directly to the printed board (PCB). After soldering, the PCB can be used as a
heatsink. In addition, through the use of thermal vias, the thermal pad can be attached directly to the appropriate
copper plane shown in the electrical schematic for the device, or alternatively, can be attached to a special
heatsink structure designed into the PCB. This design optimizes the heat transfer from the integrated circuit (IC).
For additional information on the PowerPAD package and how to use the advantage of its heat dissipating
abilities, see Technical Brief, PowerPAD Thermally Enhanced Package, Texas Instruments Literature No.
The exposed thermal pad dimensions for the PWP 14 pin and QFN 16 pin packages are shown in the Thermal
Pad Mechanical Data section of this data sheet.
