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 49. The preferred airflow direction
for the module is in Figure 50. The derating data
applies to airflow in either direction of the module’s short
axis.

The thermal reference points, T
specifications are also shown in Figure 50. For reliable
operation the temperatures at these points should not
exceed 125
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.

Modules marked ruggedized with a “D” suffix operate up
to an ambient of 105°C. For the remaining types de-
rating curves for individual output voltages meet existing
specifications up to 85°C.
