And this time it is the question: how does one turn on and off a load when the output of a Cuk converter is of the opposite polarity to the input (right).
The obvious thing is to hang a p-channel mosfet from the 0V rail and switch the load with that (left).
There seem to be a multitude of ways to drive the load-switch gate from a microcontroller connected to the input side, but most seemed to need a transistor or two.
