Control module for a resonant switched-capacitor converter and method for controlling a resonant switched-capacitor converter

Abstract

A control module, for a resonant switched-capacitor converter having first, second, third and fourth cascaded switches and generating an output voltage, includes a timing circuit generating a clock, a controller generating first and second control signals indicating, respectively, first and second control quantities, the difference between which being a function of the difference between a reference quantity and a feedback quantity depending on the output voltage, first and second delay circuits that generate first and second logic signals and, respectively, third and fourth logic signals, the first and third logic signals being delayed with respect to the clock as a function of, respectively, the first and second control quantities, the second and fourth control signals being respectively the logic negation of the first and third logic signals, and a driver that controls the first, second, third, and fourth switches based on, respectively, the first, second, third, and fourth logic signals.
