Abstract
This application relates to a power converter for a computing device. The power converter can maintain an average output current while also allowing the output current to reach a peak current limit for periods of time. The average output current is maintained by enforcing a dynamic current limit on the output current. The dynamic current limit can change over time depending on whether the average output current is above or below an average current threshold. The changes to the dynamic current limit can occur at a rate defined by one or more time constants in order to reduce electromigration and maintain a temperature of the power converter below a predetermined temperature threshold.
