Method of regulating an output voltage of a power converter by sensing the output voltage during a first time interval and calculating a next current value in an inductor sufficient to bring the output voltage to a target voltage within a second time interval immediately following the first time interval and varying a duty cycle of a switch during the second time interval

A method for regulating an output voltage applied to a load at an output terminal of a power converter, the power converter including an output capacitor coupled between the output terminal and a ground reference, and an inductor that is selectably coupled by a switch between a power supply and the ground reference, the method comprising:

• sensing the output voltage during a first time interval;
• and
• when the output voltage sensed deviates from a target value by a predetermined value;
• calculating a next current value in the inductor sufficient to bring the output voltage to a target voltage within a second time interval immediately following the first time interval;
• and
• varying a duty cycle of the switch to modify the current in the inductor during the second time interval, according to the calculated next current, the duty cycle being the portion of the second time interval during which the switch couples the inductor to the power supply.
