Efficiency is approximately 85%, this leads to an input
power of 35 watts. The case temperature rise would be 5 watts
x 4.4 = 22°C. This number is subtracted from the maximum
case temperature of 85°C to get 63°C.
This is a rough approximation of 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.
Typical Performance (Tc=25°C, Vin=Nom VDC, Rated Load).
