Abstract
A power delivery system may include 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 determine whether a voltage node in the power delivery system has fallen below a warning threshold voltage, determine whether the voltage node has fallen below a critical threshold voltage, wherein the critical threshold voltage is lesser than the warning threshold voltage, in response to a voltage of the voltage node falling below the warning threshold voltage, decrease a maximum current drawn by the power converter from a first current level to a second current level, and in response to a voltage of the voltage node falling below the critical threshold voltage, decrease a maximum current drawn by the power converter from the second current level to a third current level.
