Thermal Considerations
Power modules operate in a variety of thermal
environments; however, sufficient cooling should
always be provided to help ensure reliable
operation.
Considerations include ambient temperature,
airflow, module power dissipation, and the need for
increased reliability. A reduction in the operating
temperature of the module will result in an increase
in reliability. The thermal data presented here is
based on physical measurements taken in a wind
tunnel. The test set-up is shown in Figure 54. Note
that the airflow is parallel to the short axis of the
module as shown in Figure 55. The derating data
applies to airflow in either direction of the module’s
long axis.

The thermal reference points, T
specifications are shown in Figure 56. For reliable
operation the temperatures at these points should
not exceed 125
should not exceed the rated power of the module
(Vo,set x Io,max).
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame Board-
Mounted Power Modules” for a detailed discussion
of thermal aspects including maximum device
temperatures.
