Right. I was thinking discrete design, but if it is a module with certs you don't have many options other than keeping the noise from finding an antenna.

It cannot be over-stated that power converters that are depended on for the system's galvanic isolation and/or for providing a safe output voltage or power level should never be modified by anyone other than the original mfr.
