Abstract
A control module, for a resonant switched-capacitor converter with an inductor, includes a controller stage, an input stage generating a control signal indicating a control quantity, a delay stage generating a duration signal indicating a time quantity, and a circuit indicating zero crossings of the inductor current. If the control quantity is variable, the input stage clamps the control quantity to a control threshold. When in normal mode, the controller stage controls the converter to carry out a phase sequence with timings that depend on the zero crossings and the time quantity, so the converter generates an output current that depends on the time quantity and is prevented from dropping below a minimum current. If the output voltage reaches an upper threshold, the controller stage switches into pulse-skipping mode to suspend the phase sequence, and resumes the phase sequence after the output voltage drops to a lower threshold.
