Thermal Considerations
Power modules operate in a variety of thermal
environments; however, sufficient cooling should 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 33. Note that the airflow is
parallel to the long axis of the module as shown in
figure 32. The derating data applies to airflow in
either direction of the module’s long axis.
The thermal reference point, T
specifications of thermal derating curves is shown in
Figure 32. For reliable operation this temperature
should not exceed 125
The output power of the 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.

Heat Transfer via Convection
Increased airflow over the module enhances the heat
transfer via convection. Thermal derating curves
showing the maximum output current that can be
delivered by various module versus local ambient
temperature (T
