Anesh Selvamani

Part Number: AMC3330

Hello,

At present I am evaluating AMC3330 for one of our new developement. I have modified HV side as in the attached schematics image. This is bit diffrent from Eval board circuit. Please let me know will there be any issue.

Thankyou, Anesh S.

Hi Anesh,

This looks fine to me. If you plan to test for EMC, I recommend adding some ferrites, mainly between HGND and Neutral. You would need to separate the nets to ensure the same ferrite is effective on the other side of the sense resistor.
