Thermal Considerations
The power module operates in a variety of thermal environments; however, sufficient cooling should
be provided to help ensure reliable operation of the unit.
The thermal data presented is based on measurements taken at various airflows. Note that airflow is
parallel to the long axis of the module as shown in Figure 1 and derating applies accordingly.
Figure 1. Thermal Tests Set-Up.
The temperature at either location should not exceed 110qC. Over-temperature shutdown is
evaluated at these locations. The output power of the module should not exceed the rated power for
the module(Vo,set X Io,max).
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 actual
system, the module's temperature should be verified.
