Abstract
A method for controlling a switching voltage regulator that includes generating a feedback voltage that is proportional to the output voltage of the voltage regulator; generating a voltage proportional to the duty-cycle of the inductor charging and discharging phases as a function of the difference between the feedback voltage and a reference voltage; and adding a dominate pole and two zeros to the function used to generate the voltage proportional to the duty-cycle of the inductor charging and discharging phases.
