fcc conducted emissions
Hi,
Im using a AC to DC adapter. I then have a voltage regulator on my PCB. I did have some issues with conducted emissions however I just barely managed to pass using a linear AC to DC adapter rather than a switching.
My question is, can anyone recommend some power supply filters that I can place on my board ? The noise was coming off my board, using a better AC-DC adapter helped but didn't solve the problem.
So Im thinking I need to use some filters on my PCB. Any PDFs?
Thanks
