Abstract
A driver circuit for receiving a voltage supply at a supply input and driving a load through a load output, the circuit comprising: a charge inductor and a discharge inductor; a switching array comprising a plurality of switches; and a load switch coupled between a first terminal of the charge inductor and the load output; the switching array being arranged so that: in a first mode it can couple a second terminal of the charge inductor to the supply input and the first terminal of the charge inductor to ground to load a flux on the charge inductor; in a second mode it can decouple the first terminal of the charge inductor from ground so that, when the load switch is closed, flux can flow from the inductor to the load output; and in a third mode it can couple the discharge inductor between the load output and ground so that flux can be loaded on the discharge inductor from the load output.
