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 thermal reference points, T
specifications are also shown in Figure 50. For
reliable operation the temperatures at these points
should not exceed 120
module 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.
