20110063878 | POWER-SUPPLY CONTROLLER - An embodiment of a controller for a power supply includes circuitry that is operable to allow the power supply to operate as follows. During a first portion of a supply period, a first current flows through a first winding of the power supply, through a second winding of the power supply, and to an output node of the power supply. And during a second portion of the supply period, a second current flows through the first winding, through a third winding of the power supply, and to the output node. Each of the first, second, and third windings may be non-electrically isolated from one or more of the other windings during one or more portions of the supply period. Furthermore, the first, second, and third windings may be magnetically coupled to one another. For example, in an embodiment, such a controller may be part of a DC-DC converter that may be more efficient, and that may have reduced interdependence between output-signal ripple and transient response, than a conventional buck converter. | 03-17-2011 |
