APPLICATION INFORMATION
thermal information (continued)
The actual thermal performance achieved with the THS6032 in its PowerPAD package depends on the
application. In the previous example, if the size of the internal ground plane is approximately 3 inches
×
3 inches,
then the expected thermal coefficient,
θ
JA
,
is
about 21.5
°
C/W for the DWP package and 37.8
°
C/W for the GQE
package. For a given
θ
JA
, the maximum power dissipation is shown in Figure 40 and is calculated by the
following formula:
PD
TMAX–TA
