Abstract
A method of controlling a regulator includes turning on a first driver during a first cycle for a first time period. A second driver is turned on during the first cycle for a second time period. The first and second drivers are off during the first cycle for a third time period. The first time period is adjusted to become an adjusted first time period for a second cycle based on a ratio and a voltage difference between a peak value of the output voltage and a first voltage during the first cycle. The ratio refers to the first time period over the first time period and the second time period.
