Patent ID: 8797012

Claim:
A method for regulating an output voltage of a regulator, the method comprising: comparing the output voltage of the regulator to a reference voltage; determining a slope of the output voltage of the regulator; based on (i) the comparison of the output voltage of the regulator to the reference voltage and (ii) the slope of the output voltage of the regulator, selecting a duty cycle from a plurality of duty cycles, wherein the plurality of duty cycles comprise (i) a first duty cycle, (ii) a second duty cycle, (iii) a third duty cycle, and (iv) a fourth duty cycle, and wherein selecting the duty cycle further comprises selecting the first duty cycle when (i) the output voltage of the regulator is greater than the reference voltage and (ii) the determined slope of the output voltage of the regulator is positive, selecting the second duty cycle when (i) the output voltage of the regulator is greater than the reference voltage and (ii) the slope of the output voltage of the regulator is negative, selecting the third duty cycle when (iii) the output voltage of the regulator is less than the reference voltage and (ii) the slope of the output voltage of the regulator is positive, and selecting the fourth duty cycle when (i) the output voltage of the regulator is less than the reference voltage and (ii) the slope of the output voltage of the regulator is negative; and based on the selected duty cycle, regulating the output voltage of the regulator.
