APPLICATION INFORMATION
general PowerPAD
design considerations
The THS408x is available packaged in a thermally-enhanced DGN package, which is a member of the
PowerPAD
family of packages. This package is constructed using a downset leadframe upon which the die
is mounted [see Figure 44(a) and Figure 44(b)]. This arrangement results in the lead frame being exposed as
a thermal pad on the underside of the package [see Figure 44(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 the
surface mount with the, heretofore, awkward mechanical methods of heatsinking.
