摘要： In accordance with an embodiment, a method includes conducting a reverse current through a first switch that includes a normally-on transistor coupled in series with a normally-off transistor between a first switch node and a second switch node. While conducting the reverse current, the first switch is turned-off by turning-off the normally-off transistor via a control node of the normally-off transistor and reducing a drive voltage of the normally-on transistor by decreasing a voltage between the control node of the normally-on transistor and a reference node of the normally-on transistor. After turning-off the first switch, a second switch coupled to the first switch is turned on.
