Abstract
A control circuit of a three-level DC-DC converter, can include where: the three-level DC-DC converter includes first, second, third, and fourth power switches coupled in series between an input voltage and a reference ground, and a flying capacitor coupled between a common node of the first and second power switches and a common node of the third and fourth power switches; and the control circuit is configured to adjust a phase difference between driving signals of the first and second power switches, and duty ratios of the first and second power switches, according to an error between a voltage across the flying capacitor and a predetermined value, such that the voltage across the flying capacitor is stabilized at the predetermined value.
