Thermal Considerations
The power module operates in a variety of thermal environ-
ments; 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 wind tunnel. The test setup shown in Figure 25
was used to collect data for Figures 26
and 27. Note that the airflow is parallel to the long axis of the
module as shown in Figure 24 and derating applies accord-
ingly.
Figure 24. Temperature Measurement Location .
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).

Convection Requirements for cooling
To predict the approximate cooling needed for the module,
refer to the Power Derating curves in Figures 26 and 27.
These derating curves are approximations of the ambient
temperatures and airflows required to keep the power mod-
ule temperature below its maximum rating. Once the module
is assembled in the actual system, the module’s temperature
should be checked as shown in Figure 24 to ensure it does
not exceed 110 °C.
Proper cooling can be verified by measuring the power mod-
ule’s temperature at Q1-pin 6 and Q2-pin 6 as shown in Fig-
ure 24.
