Abstract
A method may include controlling switching behavior of switches of a switch-mode power supply based on a desired physical quantity associated with the switch-mode power supply, wherein the desired physical quantity is based at least in part on a slope compensation signal, generating the slope compensation signal to have a compensation value of approximately zero as seen by a compensation control loop of the switch-mode power supply, and modifying the slope compensation signal on successive switching cycles of the switch-mode power supply to account for differences in an output of the compensation control loop and an average current of an inductor of the switch-mode power supply in at least one phase of a switching period of a switching cycle of the switch-mode power supply.
