8.16.5.2 Default Enhanced Thermal Solution
If you have no control over the end-user’s thermal environment, or if you wish to bypass the thermal
modeling and evaluation process, use the Default Enhanced Thermal Solutions. This solution replicates
the performance defined at the Thermal Design Power (TDP). If, after implementing the Recommended
Enhanced Thermal Solution, the case temperature continues to exceed allowable values, then
additional cooling is needed. This additional cooling may be achieved by improving airflow to the
component and/or adding additional thermal enhancements. A 40x40x10mm active heat sink is an
alternative to the passive heat sink.
8.16.5.3 Extruded Heatsinks
If required, the following extruded heatsinks are the suggested. Figure 8-13 shows a passive and an
active heatsink drawing.
