I'm living off grid with a 24V battery system (actually 25-29V).
My music comes from a raspberry pi fed from a buck converter.
The system works great, but all the buck converters I've tried have been a bit noisy. It's the same sort of noise you get if you plug your phone into three aux in of a car stereo, while charging via the cigarette lighter.
I don't have a lot of battery storage so I'm trying to make everything as efficient as possible, else I'd probably throw a couple of 317s at it. What would filter the noise?
I think current draw is normally under 500mA but peak current could exceed 2A.
I was thinking of CLCLC or a VBE but don't really know about the effectiveness in this setup.
