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 and generating the slope compensation signal to have a compensation value of approximately zero at an end of a duty cycle of operation of the switch-mode power supply.
