Thermal Considerations (continued)
The preferred airflow direction and the thermal reference points, T
below. For reliable operation the temperatures at these points should not exceed 125
module should not exceed the rated power of the module (Vo,set x Io,max). The derating data applies to airflow
in either direction of the module’s short axis.
