Abstract: A converter circuit arrangement is provided, including a converter switch controller, a converter switch, a load circuit interface and an inductor. The converter switch controller may include a control input. The converter switch may be coupled between a first power supply potential and the control input. The inductor may be coupled between a second power supply potential and the load circuit interface. The load circuit interface may be coupled between the control input and the inductor.

Abstract: In accordance with an embodiment, a circuit includes a first transistor, a second transistor having a reference node coupled to an output node of the first transistor, and a control circuit. The control circuit is configured to couple a second reference node to a control terminal of the second transistor during a first mode of operation, couple a floating reference voltage between the control terminal of the second transistor and the reference terminal of the second transistor during a second mode of operation and during a third mode of operation, and couple a third reference node to the reference terminal of the second transistor during the third mode of operation. The second reference node is configured to have a voltage potential operable to turn-on the second transistor, and the floating reference voltage is operable to turn on the second transistor.
