I almost understood that part just above, where the buck converter tries to balance the power at its input with the power being used at its output. It has to find a voltage at the input that will get the power down to what is being used at the output.

Suspect that it is the buck converter as directed by the microprocessor that is doing this. Not the buck converter by itself.

Well my little buck converter gizmo by itself was hopeless. It got saturated and all that. Then I was told here it needed a bunch of other circuits stuck on so it would behave properly.
