Abstract
A power adapter provides power to an information handling system. The power adapter includes a power supply and a power delivery controller. The power supply receives an alternating current (AC) input at one of a plurality of input voltages, and provides a direct current (DC) output at one of a plurality of output voltages, each output voltage being associated with a current limit. The power delivery controller determines, upon being plugged into an AC power source, a first input voltage of the AC power source, determines a DC power delivery capability of the information handling system, sets a first output voltage and a first current limit of the power supply DC output based upon the first input voltage and the DC power delivery capability, the first output voltage and the first current limit defining a first power limit to the information handling system, determines that the power supply can provide a second power limit that is greater than the first power limit based upon an operating condition of the power supply, and communicates the second power limit to the information handling system.
