QCan these Isolated supplies be used with 3V3 to the non-isolated supply input
pin VDDA with the Isolated supply Primary at 5V supplying its common pin VDD1.
The secondary (Isolated) output supply could be 3V3 or 5V or even 12V in our
applications. - CLARIFICATION:- We want to have a 3.3V digital Interface on the
non-isolated interface (A) but use a 5V power supply to provide the power for
the secondary (Isolated) supply driver (X1-X2).
Is this allowed? Please advise us of any precautions or dangers.
