APPLICATION INFORMATION
general PowerPAD design considerations (continued)
The actual thermal performance achieved with the THS6072DGN in its PowerPAD package depends on the
application. In the example above, if the size of the internal ground plane is approximately 3 inches
×
3 inches,
then the expected thermal coefficient,
θ
JA
,
is
about 58.4 C/W. For comparison, the non-PowerPAD version of
the THS6072 IC (SOIC) is shown. For a given
θ
JA
, the maximum power dissipation is shown in Figure 47 and
is calculated by the following formula:
