I think most of the squealing actually comes from DC-DC conversion.

Huh, I figured there had to be AC in there somewhere because otherwise where is the frequency coming from? Or is there a conversion to AC somewhere in the middle of a DC-DC conversion? I had assumed you could achieve it with just resistors. I am ignorant about the physical nature of electronics.
