Classification: CPC H  Y | IPC H

Claim 13:
14. A method of operating a power circuit comprising a Logic Power Supply (LPS) coupled to an input, the method comprising:
receiving input power from an input source at the input;
operating the LPS to convert the input power into output power;
operating the LPS to provide, in a first mode of operation, the output power with a first voltage level to a first output via a first switch in response to receiving an indication that a load coupled to the output is being powered by the output power;
operating the LPS to provide, in a second mode of operation, the output power with a second voltage level to the first switch in response to receiving an indication that the load is not being powered by the output power, the second voltage level being generated by the LPS based on a level sufficient to power a controller coupled to the power circuit;
coupling, with the first switch, the LPS to the output in the first mode of operation;
decoupling, with the first switch, the LPS from the output in the second mode of operation;
converting, in the second mode of operation with a converter coupled to the LPS and a second output, the output power with the second voltage level into converter output power; and
providing, in the second mode of operation, the converter output power to the controller via the second output to power the controller,
wherein the second output is disconnected from the first output such that the second output does not provide power to the first switch.
