Hello,
I am designing an LED board that is driven by Switching regulator(Buck) the Buck regulator frequency will be running anywhere between 200~ 300 Khz.
Now the board has to pass the conducted RF interference test and conform to the chart below.
Is it good idea to use Pi filter at the input ? What's a good design practice and how do i go about designing this filter so that i comply with the requirement in the chart?
Thank you
