[ARC5] DC-DC Buck/Boost Converter Regulation

[Dennis Monticelli]

Yes.  This can happen when the RF gets in via the input or output wires.
The output could end up doing anything.   Another reason for putting in the
low pass filtering when you're building something.  If you're applying
something already built then use a ferrite choke or beads.
