摘要： Disclosed are systems, devices, circuits, components, mechanisms, and processes in which a switching mechanism can be coupled between components. The switching mechanism is configured to have an on state or an off state, where the on state allows current to pass along a current path. A monitoring mechanism has one or more sensing inputs coupled to sense an electrical characteristic at the current path. The electrical characteristic can be a current, voltage, and/or power by way of example. The monitoring mechanism is configured to output a reporting signal indicating the sensed electrical characteristic. The monitoring mechanism can be integrated with the switching mechanism on a chip.

摘要： An integrated circuit chip includes a first input port, a first output port, and first and second transistors electrically coupled in series across the first input port. The second transistor is also electrically coupled across the first output port and is adapted to provide a path for current flowing through the first output port when the first transistor is in its non-conductive state. The integrated circuit chip additionally includes first driver circuitry for driving gates of the first and second transistors to cause the transistors to switch between their conductive and non-conductive states. The integrated circuit chip further includes first controller circuitry for controlling the first driver circuitry such that the first and second transistors switch between their conductive and non-conductive states to at least substantially maximize an amount of electric power extracted from an electric power source electrically coupled to the first input port.

摘要： An electric power system includes N electric power sources and N switching circuits, where N is an integer greater than one. Each switching circuit includes an input port electrically coupled to a respective one of the N electric power sources, an output port, and a first switching device adapted to switch between its conductive and non-conductive states to transfer power from the input port to the output port. The output ports of the N switching circuits are electrically coupled in series and to a load to establish an output circuit. Each of the N switching circuits uses an interconnection inductance of the output circuit as a primary energy storage inductance of the switching circuit.

摘要： An inductor includes a core formed of a magnetic material and a foil winding wound at least partially around or through at least a portion of the core. A first end of the winding extends away from the core to form an extended output tongue configured and arranged to supplement or serve as a substitute for a printed circuit board foil trace. A second end of the winding forms a solder tab. At least a portion of the extended output tongue and the solder tab are formed at a same height relative to a bottom surface of the core. Another inductor includes a core formed of a magnetic material, a winding wound at least partially around or through at least a portion of the core, and a ground return conductor attached to the core. The core does not form a magnetic path loop around the ground return conductor.

摘要： An asymmetrical coupled inductor includes a first and a second winding and a core. The core is formed of a magnetic material and magnetically couples together the windings. The core is configured such that a leakage inductance value of the first winding is greater than a leakage inductance value of the second winding. The coupled inductor is included, for example, in a multi-phase DC-to-DC converter. A DC-to-DC converter including a symmetrical coupled inductor includes at least one additional inductor electrically coupled in series with one or more of the coupled inductor's windings. A controller for a DC-to-DC converter including a first phase having an effective inductance value greater than an effective inductance value of a second phase is configured to shut down the second phase while the first phase remains operational during a light load operating condition.
