ADAPTIVE MULTIMODE USB-C POWER TRANSMISSION AND CONVERSION

Systems and methods are provided for adaptively powering an Information Handling System (IHS) using a multimode AC adapter. Information reported by the multimode adapter is utilized to determine whether it supports USB-PD power transmissions and also supports high-power transmissions. The power demand of the IHS is monitored. When the power demand is greater than the USB-PD power levels, the multimode adapter is configured for providing a high-power transmission and a power circuit of the IHS is configured for converting the high-power transmission to a voltage used by the IHS. When the power demand is not greater than the USB-PD power levels, the multimode adapter is configured for providing a USB-PD transmission. Some embodiments may detect events associated with high power demand and may preemptively configure the power circuit of the IHS for providing high-power outputs upon detecting such events.
