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 45. The preferred airflow direction
for the module is shown in Figure 46.
The thermal reference points, T
specifications are shown in Figure 46. 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.
