  • Providing a wide variety of voltages with a power supply that uses an LLC topology
    Patent number: 11437914
    Abstract: As an example, a power supply may provide a particular voltage of multiple voltages based on a power profile provided by a universal serial bus Type C (USB-C) integrated circuit (IC) built-in to a USB-C port of a computing device. A power factor correction (PFC) converter may provide an output voltage that varies according to the power profile. The output voltage of the PFC converter may be used as an input to an inductor-inductor-capacitor (LLC) converter. The LLC converter may produce an output voltage that varies in voltage level proportionally to the PFC converter output voltage. The PFC converter may provide a voltage to the LLC converter that causes the LLC converter to provide an amount of voltage indicated in the power profile sent by the USB-C IC of the computing device.

  • METHODS FOR FORMING CAPACITOR STRUCTURES
    Publication number: 20080299723
    Abstract: A method for forming a capacitor includes forming a dielectric layer over a substrate. A conductive layer is formed over the dielectric layer. Dopants are implanted through at least one of the dielectric layer and the conductive layer after forming the dielectric layer so as to form a conductive region under the dielectric layer, wherein the conductive layer is a top electrode of the capacitor and the conductive region is a bottom electrode of the capacitor.
