Abstract
This document discusses methods and apparatus for converting an input voltage level to an output voltage level that can be different from the input voltage level. In an example, a converter can include a first switch configured to couple an inductor to a load, a second switch configured to initiate current flow in the inductor, a third switch coupled to a current source, and a controller configured to couple the first switch to the third switch to form a current mirror, to conduct current between the inductor and the load using the first switch, and to control the conducted current using the current source when an output voltage is substantially less than the supply voltage.
