Abstract
An embodiment of a power-supply controller is operable to couple a first node of a first inductor to first and second reference nodes, the first inductor composing a first phase of a power supply and having a second node coupled to an output node of the power supply. The controller is also operable to couple a first node of a second inductor to third and fourth reference nodes, the second inductor composing a second phase of the power supply and having a second node. Furthermore, the controller is operable to uncouple the second node of the second inductor from the output node of the power supply. For example, where the first and second inductors are magnetically coupled, such a controller allows the power supply to operate as an uncoupled-inductor (UI) power supply in one mode, and as a coupled-inductor (CI) power supply in another mode.
