This example calculation is for an LV Single without any
extra heat sinking or appreciable air flow. Both of these factors
can greatly effect the maximum ambient temperature. Exact
efficiency depends on input line and load conditions, check
the efficiency curves for exact information.
This is a rough approximation to the maximum ambient
temperature. Because of the difficulty of defining ambient
temperature and the possibility that the loads dissipation may
actually increase the local ambient temperature significantly,
these calculations should be verified by actual measurement
before committing to a production design.
Remember, it is the system designers responsibility to be
sure that the case temperature of the LV Single does not
exceed 85°C for maximum reliability in operation.
