A controller configured to control a power conversion circuit, the controller comprising:

• at least a first conductor configured to couple to a first plurality of switches comprising:
• a first switch having an input coupled to a first voltage source and an output coupled to an input terminal of an inductor;
• and
• a second switch having an input coupled to a second voltage source and an output coupled to the input terminal of the inductor;
• at least a second conductor configured to couple to a second plurality of switches comprising:
• a third switch having an input coupled to an output terminal of the inductor and an output coupled to a terminal configured to carry a signal at a first voltage;
• and
• a fourth switch having an input coupled to the output terminal of the inductor and an output coupled to a terminal configured to carry a signal at a second voltage;
• and
• circuitry configured to:

• and
• selectively open and close one of the first switch and the second switch and the fourth switch to cause the terminal coupled to the output of the fourth switch to carry the signal at the second voltage based on one or more parameters associated with the first voltage source and one or more parameters associated with the second voltage source.
