I tried to replace the inductor with another brand and bigger size (higher current rating) inductor, the noise seems reduced slightly (the original inductor’s current rating is about double of the converter’s output current already), and both of them are shielded inductor with EPOXY potted already, so more EPOXY may not be helped. Anyone can share some experience knowledge with me on how to solve this issue? And any reply will be appreciated
