APPLICATION INFORMATION
designing with PowerPAD
(continued)
It is recommended that there be a thermal land, which is an area of solder-tinned-copper, underneath the
PowerPAD package. The thermal land varies in size depending on the PowerPAD package being used, the PCB
construction, and the amount of heat that needs to be removed. In addition, the thermal land may or may not
contain numerous thermal vias depending on PCB construction.
Other requirements for thermal lands and thermal vias are detailed in the TI application note
PowerPAD
Thermally Enhanced Package Application Report
, TI literature number SLMA002, available via the TI Web
pages beginning at URL:

Figure 13. Example of a Thermal Land
For the TLK2201A, this thermal land must be grounded to the low-impedance ground plane of the device. This
improves not only thermal performance but also the electrical grounding of the device. It is also recommended
that the device ground pin landing pads be connected directly to the grounded thermal land. The land size must
be as large as possible without shorting device signal pins. The thermal land may be soldered to the exposed
PowerPAD using standard reflow soldering techniques.
While the thermal land may be electrically floated and configured to remove heat to an external heat sink,
it is
recommended
that the thermal land be connected to the low-impedance ground plane for the device. More
information may be obtained from the TI application note
