Abstract
In accordance with an embodiment, a method of operating a switch-mode power supply includes receiving a measurement of a first current of the switch-mode power supply, determining a ripple of the first current based on the received measurement of the first current, determining a maximum current threshold based on a target average current and the determined ripple of the first current, determining an off time of a switch based on a target current ripple and the determined ripple of the first current, turning off the switch when the first current reaches the maximum current threshold, and turning on the switch after the determined off time has elapsed after turning off the switch.
