Classification: CPC G  H | IPC G

Claim 8:
9. A method to provide power to an information handling system, the method comprising:
receiving, by a power supply of a power adapter, an alternating current (AC) input at one of a plurality of input voltages;
providing, by the power supply, a direct current (DC) output to the information handling system at one of a plurality of output voltages, each output voltage being associated with a current limit; and
determining, by a power delivery controller, upon being plugged into an AC power source, a first input voltage of the AC power source;
determining DC power delivery capability of the information handling system;
setting 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; and
determining that the power supply can provide a second power limit that is less than the first power limit based upon an operating condition of the power supply, wherein the operating condition includes a frequency of the AC power source.
