| Abstract: | The theoretical and practical details involved in the control design and closed-loop analysis of a step-down switched-capacitor (SC) DC-to-DC converter are presented. The state-space averaging technique is applied to extract the small-signal dynamics of the power stage, and a graphical loop gain method is used to design the feedback compensation and analyze the closed-loop performance of an SC converter. The results of the control design and closed-loop analysis are substantiated by experiments using a prototype SC converter |
