Abstract
One embodiment of the invention includes a regulator system that includes a high-side power transistor electrically connected between a first node and a second node. The system also includes a low-side power transistor electrically connected between the second node and a third node. The high and low-side power transistors can be controlled by high and low-side control signals, respectively. A mode controller provides at least one mode control signal having a value to enable operation of the regulator system in each of a buck switching, boost switching, negative switching, and linear regulator mode. The regulator system can utilize at least one of the high-side power transistor and the low-side power transistor to operate in the selected mode depending on at least one of an input voltage and an arrangement of external circuitry that are electrically coupled to at least one of the first, second, and third nodes to provide a regulated output voltage.
