Multimode usb-c power transmission and conversion

An Information Handling System (IHS) comprising:

• one or more processors;
• a memory device coupled to the one or more processors, the memory device storing computer-readable instructions that, upon execution by the one or more processors, cause execution of an operating system of the IHS;
• and
• an embedded controller comprising a memory having program instructions stored thereon that, upon execution by a logic unit of the embedded controller, cause the embedded controller to:
• detect a coupling of a multimode AC adapter to a USB-C port of the IHS, wherein the USB-C port supports receipt of a plurality of USB-PD voltages;
• determine, based on information reported by the multimode AC adapter, when the multimode AC adapter supports transmission of a high-power output to the USB-C port, wherein the high-power output comprises a voltage greater than the USB-PD voltages;
• negotiate aspects of the high-power output by the multimode AC adapter via the USB-C port;
• and
• configure a power circuit of the IHS for converting the negotiated high-power output to an input utilized by the IHS.

A method for powering an Information Handling System (IHS) using a multimode AC adapter, the method comprising:

• detecting a coupling of a multimode AC adapter to a USB-C port of the IHS, wherein the USB-C port supports receipt of a plurality of USB-PD voltages;
• determining, based on information reported by the multimode AC adapter, when the multimode AC adapter supports transmission of a high-power output to the USB-C port, wherein the high-power output comprises a voltage greater than the USB-PD voltages;
• negotiating aspects of the high-power output by the multimode AC adapter via the USB-C port;
• configuring a power circuit of the IHS for converting the negotiated high-power output to an input utilized by the IHS;
• powering the IHS using the input converted by the power circuit, wherein the input generated by the operation of the power circuit comprises greater than 200 watts of power.
