Abstract
A switch control circuit may be utilized for a sequence of switching events: a first event to activate a first switch and deactivate a second switch, wherein a current of an inductor coupled to the first switch and the second switch increases during the first event and has a positive value at an end of the first event; a second event to deactivate the first switch and activate the second switch, wherein the current of an inductor coupled to the first switch and the second switch decreases during the second event; and an impedance event during one of the first event and the second event such that during one of the first event and the second event, the impedance event causes an impedance of the one of the first switch and the second switch to decrease.
