    Abstract: Methods and apparatus to increase efficiency of a power converter using a bias voltage on a low side drive gate are disclosed. An example power converter includes an inductor; a transistor coupled to the inductor; and a driver coupled to a gate of the transistor, the driver to apply (A) a first voltage to the gate to enable the transistor, (B) a second voltage to the gate to disable the transistor, and (C) a third voltage to the gate during a transition between applying the first voltage and the second voltage, the third voltage being between the first voltage and the second voltage.

    Abstract: A galvanic isolation device includes a first integrated circuit (IC) die that has communication circuitry formed in a circuit layer below the top surface. A first conductive plate is formed on the IC die proximate the top surface, and is coupled to the communication circuitry. A dielectric isolation layer is formed over a portion of the top surface of the IC after the IC is fabricated such that the dielectric isolation layer completely covers the conductive plate. A second conductive plate is juxtaposed with the first conductive plate but separated by the dielectric isolation layer such that the first conductive plate and the second conductive plate form a capacitor. The second conductive plate is configured to be coupled to a second communication circuit.

    Abstract: In some embodiments, a system comprises a power metal oxide semiconductor field effect transistor (MOSFET) configured to provide power in the system, a plurality of auxiliary MOSFETs, and a switch network configured to switchably and simultaneously couple a first of the plurality of auxiliary MOSFETs to the power MOSFET and a second of the plurality of auxiliary MOSFETs to a feedback voltage regulator. The switch network is further configured to switchably and simultaneously couple the first of the plurality of auxiliary MOSFETs to the feedback voltage regulator and the second of the plurality of auxiliary MOSFETs to the power MOSFET. The feedback voltage regulator is configured to cause a voltage at one or more of the plurality of auxiliary MOSFETs to match a voltage at the power MOSFET.
