Abstract
A DC-DC converter includes an inductor, and generates a regulated voltage from a power source. The current flow through the inductor is increased at a first rate in a first interval. In a second interval, the current flow through the inductor is either increased at a second rate or decreased at a third rate depending on whether the regulated voltage is required to be respectively less than or greater than a voltage of the power source. The current flow through the inductor is decreased at a fourth rate in a third interval. The sequence formed by the first interval, the second interval and the third interval is repeated, and followed for all values of the regulated voltage from a lower threshold to higher threshold. The higher threshold has a value greater than the voltage of the power source. The lower threshold is zero volts.
