Classification: CPC G  H | IPC G

Claim 0:
1. A power adapter to provide power to an information handling system, the power adapter comprising:
a power supply configured to receive an alternating current (AC) input at one of a plurality of input voltages, and to provide a direct current (DC) output at one of a plurality of output voltages, each output voltage being associated with a current limit; and
a power delivery controller configured to:
determine, upon being plugged into an AC power source, a first input voltage of the AC power source;
determine a DC power delivery capability of the information handling system;
set 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;
determine 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; and
communicate the second power limit to the information handling system.
