    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.

The coupled inductor further includes at least one top magnetic element adjacent to and extending at least partially over at least two of the M connecting magnetic elements to provide a magnetic flux path between the first and second end magnetic elements. The inductor may be included in an M-phase power supply, and the power supply may at least partially power a computer processor.

    摘要: A circuit includes a first input terminal for receiving a first pulsed voltage and a second input terminal for receiving a second pulsed voltage. The circuit further includes a load and an LC filter. The LC filter includes a coupled inductor pair that includes a first winding and a second winding magnetically coupled to each other. The first winding is coupled between the first input terminal and the load, and the second winding is coupled between the second input terminal and the load. A frequency of a first current flowing through the first winding is increased by the second pulsed voltage applied to the second winding.

    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.

    摘要: A laser device includes a plurality of lasers that includes a first laser and a second laser. The laser device further includes a drive circuit configured to apply a pulsed current to the first laser at a first phase. The drive circuit is further configured to apply the pulsed current to the second laser at a second phase. The first phase and the second phase are different. A total voltage provided to the plurality of lasers during a period between the first and second phases is substantially smaller than a sum of individual voltages provided to the plurality of lasers, respectively, during a pulse period of the pulsed current.
