Claim Text:
1. A device, comprising: a first switch, a first load terminal of the first switch being coupled with a first voltage input and a second load terminal of the first switch being coupled with an output node, a second switch, a first load terminal of the second switch being coupled with the output node and a second load terminal of the second switch being coupled with a second voltage input, and a controller, the controller being coupled to a control input of the first switch and a control input of the second switch, wherein the controller is adapted to control the first switch and the second switch selectively in a first mode of operation or a second mode of operation, the controller being adapted to change from the second mode of operation to the first mode of operation based on a time where both the first and second switches are open, and wherein the controller is adapted to change from the second mode to the first mode based on a ratio between the time where both the first and second switches are open and a time where at least one of the first switch or the second switch is closed.
