ADuM3470 efficiency over temperature range

Q

Have you any information concerning efficiency and power consumption changes
with temperature - -40C to +85C?

Are the efficiency figures for 5V in 5V out applicable to my application with
the Primary digital side supplied by 3v3.

A

From our characterization data, the ADuM347x efficiency from 5V in to 5Vout
over temperature has a minimum of about 68%. I checked with the designers about
applying these efficiency figures for VDDA supplied by 3.3V, and they said it
should be about the same.
