Thermal Considerations
The power module operates in a variety of thermal environments; however, suf-
ficient cooling should be provided to help ensure reliable operation of the unit.
The thermal data presented is based on measurements taken at various
airflows. Note that airflow is parallel to the long axis of the module as shown in
Figure 1 and derating applies accordingly.
As a rule of thumb however, we recommend to use a normal-blow or
slow-blow fuse with a typical value of about twice the maximum input current,
calculated at low line with the converter’s minimum efficiency.
The temperature at the thermal measurement location (TML) 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 2–17.
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 actualsystem, the module’s tem-
perature should be verified.
