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 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： A multiple-output DC-DC converter has a first and a second DC-DC sub-converter, each DC-DC subconverter may be a buck, boost, or buck-boost converter having a primary energy-storage inductor. Each DC-DC subconverter drives a separate output of the multiple-output converter and typically has a separate feedback control circuit for controlling output voltage and/or current. The converter has a common timing circuit to maintain a phase offset between the first and DC-DC subconverters. The primary energy storage inductors of the first and second DC-DC converter are magnetically coupled to raise an effective ripple frequency of the converter and simplify output filtering.
