1. A power delivery system, comprising:
a power converter configured to electrically couple to a power source and further configured to supply electrical energy to one or more loads electrically coupled to an output of the power converter; and
control circuitry configured to:
monitor a first voltage derived from the power source, wherein the first voltage is indicative of a total power demanded by the power converter; and
control a limit for a current supplied from the power source to the one or more loads based on comparison of the first voltage to a threshold voltage, wherein the threshold voltage is indicative of a point within a range of operation of the power converter at which the power converter delivers a maximum amount of power to the one or more loads.
