Abstract
Driver circuitry including an inductor configured to be used both as an inductor of a buck converter and to provide high-speed pulse driving of a load. The driver circuitry includes the buck converter, which includes a first switch, a second switch and a comparator configured to drive the first switch and the second switch. The inductor is connected between the first switch and the second switch of the buck converter and the load and supplies current to drive the load.
