摘要： An inductor includes a core (1514) formed of a magnetic material and a foil winding (1506) 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 (1604) 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 (1504). 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 (1508, 1510) 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.
