ADuM4472 Primary side: 5V power and 3V3 digital, Secondary side: all 5V

I would like to use this powerfull IC in the following configuration:

Primary side voltages:

  • IC power supply (Pin#8 Vdda): 3V3
  • Transformer power supply (Center tap): 5V

Secondary (isolated) side voltages:

  • 5V

I would like to achive:

  • 5V to 5V power isolation (with 2,5W output power!)
  • Data isolation between 3V3 digital primary side and 5V digital secondary side

(So basically I will use this chip in its 3V3 / 5V configuration, but with a separate 5V power supply for the transformer (1CT:2CT) on the primary side to get the 2,5W output power rating.)

Can somebody confirm that this IC is capable of this operation?

Thank you very much for any help in advance!

Best regards,
