A method of controlling a DC-DC step-up converter including at least one power switch and an energy storage inductor may include comparing a converter output voltage to a first threshold and generating a first comparison flag based on the converter output voltage comparison. The method may also include comparing a voltage across the energy storage inductor to a second threshold and generating a second comparison flag based on the second energy storage inductor voltage comparison. The method may further include controlling the at least one power switch as a function of a logic state of the first comparison flag and the second comparison flag, and stepwise adjusting the second threshold as a function of the first comparison flag and the second comparison flag to limit a ripple on the converter output voltage.
