SLOS335A – DECEMBER 2000 – REVISED OCTOBER 2004
The thermally enhanced PWP package is based on the 24-pin TSSOP, but includes a thermal pad (see Figure
36) to provide an effective thermal contact between the IC and the PWB.
Traditionally, surface mount and power have been mutually exclusive terms. A variety of scaled-down
TO-220-type packages have leads formed as gull wings to make them applicable for surface-mount applications.
These packages, however, have only two shortcomings: they do not address the low profile (< 2 mm)
requirements of many of today's advanced systems, and they do not offer a terminal-count high enough to
accommodate increasing integration. On the other hand, traditional low-power, surface-mount packages require
power-dissipation derating that severely limits the usable range of many high-performance analog circuits.
The PowerPAD package (thermally enhanced TSSOP) combines fine-pitch, surface-mount technology with
thermal performance comparable to much larger power packages.
The PowerPAD package is designed to optimize the heat transfer to the PWB. Because of the small size and
limited mass of a TSSOP package, thermal enhancement is achieved by improving the thermal conduction paths
that remove heat from the component. The thermal pad is formed using a patented lead-frame design and
manufacturing technique to provide a direct connection to the heat-generating IC. When this pad is soldered or
otherwise thermally coupled to an external heat dissipator, high power dissipation in the ultrathin, fine-pitch,
surface-mount package can be reliably achieved.
