Convection Requirements for Cooling
To predict the approximate cooling needed for the module, refer to the Power
Derating Curves in Figures 2–17.
These derating curve are approximations of the ambient temperature and
airflow required to keep the power module temperature below it’s maximum
rating. Once the module is assembled in the actualsystem, the module’s tem-
perature should be verified.
