APPLICATION INFORMATION
general PowerPAD design considerations
The TLC08x is available in a thermally-enhanced PowerPAD family of packages. These packages are
constructed using a downset leadframe upon which the die is mounted [see Figure 52(a) and Figure 52(b)]. This
arrangement results in the lead frame being exposed as a thermal pad on the underside of the package [see
Figure 52(c)]. Because this thermal pad has direct thermal contact with the die, excellent thermal performance
can be achieved by providing a good thermal path away from the thermal pad.
The PowerPAD package allows for both assembly and thermal management in one manufacturing operation.
During the surface-mount solder operation (when the leads are being soldered), the thermal pad can also be
soldered to a copper area underneath the package. Through the use of thermal paths within this copper area,
heat can be conducted away from the package into either a ground plane or other heat dissipating device.
The PowerPAD package represents a breakthrough in combining the small area and ease of assembly of
surface mount with the, heretofore, awkward mechanical methods of heatsinking.

Although there are many ways to properly heatsink the PowerPAD package, the following steps illustrate the
recommended approach.
