Innoswitch3-Ep in non-isolated flyback
Posted by: E.A.

Hi,
I have depeloped a 50W isolated flyback with INN3678C-H606. Now, for another application, I need to use the same circuit but in not-isolated version. My question is if it is possible to connect the GND pin to the negative pole of the AC bridge rectifier, making a non-isolated flyback topology.
Do you see any problem for that? I attached an image with this connection in red.
Thank you.

Hi E.A.
Thank you for participating in our PI forum.
Yes, implementing it that way should be fine. Though, we recommend to connect it and make a star connection to the GND terminal of your input capacitor instead.
