Abstract: A transformer respectively includes a first isolation barrier, a first inductive element, a second isolation barrier, and a second inductive element. The first isolation barrier and second isolation barrier each comprise multiple isolation layers. The transformer also includes magnetic material including a top magnetic portion disposed above the first isolation barrier. The transformer also includes a bottom magnetic portion disposed below the second inductive element; The transformer further includes an intermediary magnetic portion extending from the top magnetic portion to the bottom magnetic portion via a through-hole within the first isolation barrier, first inductive element, second isolation barrier, and second inductive element. The transformer yet further includes at least one lateral magnetic portion extending from the top magnetic portion to the bottom magnetic portion. The at least one lateral magnetic portion is disposed laterally from the first isolation barrier, first inductive element, second isolation barrier, and second inductive element.

Abstract: An integrated circuit (IC) package comprises a semiconductor die, a leadframe comprising a plurality of leads coupled to bond pads on the semiconductor die, and an electrically conductive member electrically coupled to the leadframe. A magnetic mold compound encapsulates the electrically conductive member to form an inductor. A non-magnetic mold compound encapsulates the semiconductor die, the leadframe, and the magnetic mold compound.

Abstract: In at least some embodiments, a system comprises a frequency generator configured to generate a second clock signal having a second frequency using a first clock signal having a first frequency. The second frequency is offset from the first frequency and each of a plurality of harmonic frequencies of the second frequency is offset from a harmonic frequency of the first frequency. The system also includes a power converter configured to produce a power signal that at least partially corresponds to the second frequency. The system further comprises an analog-to-digital converter (ADC) configured to sample and convert analog voltages at the first frequency. The ADC is powered by the power signal.
