ADUM5401 device has the capability to choose between a 3.3V output and 5V
output on the isolated side via pin 10 (Vsel). My question is the following: Is
the 5V output also available when Vcc on the primary side is only 3.3V? So is
the integrated DC/DC converter capable of boosting 3.3V to 5V or do I have the
choice between 3.3V and 5V ouput only if Vcc on the primary side is 5V?

 

The integrated DC/DC converter is not capable of boosting 3.3V to 5V, you must
choice between 3.3V and 5V if Vcc on the primary side is 5V.
