Thermal Considerations
Convection Requirements for Cooling
To predict the approximate cooling needed for the module, refer to the Power Derating Curve in
Figure 2 to Figure 8.
These derating curve are approximations of the ambient temperature and airflow required to keep the
power module temperature below it's maximum rating. Once the module is assembled in the actual
system, the module's temperature should be verified.
Proper cooling can be verified by measuring the power module's temperature at Q1-pin 6 and Q2-pin
6 as shown in Figure 1.
The power module operates in a variety of thermal environments; however, sufficient cooling
should be provided to help ensure reliable operation of the unit. Heat is removed by
conduction, convection, and radiation to the surrounding environment. The thermal data
presented is based on measurements taken in a set-up as shown in fig 1. when the airflow is
parallel to the long axis of the module. The de-rating applies accordingly.
The temperature at either location should not exceed 110 °C. The output power of the module
should not exceed the rated power for the module (VO, set x IO, max)
