摘要： 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.
