Abstract: The present disclosure includes a feedback system that can control hybrid regulator topologies that have multiple converters or regulators connected in series. The hybrid regulator can include at least two regulators: a switched inductor regulator and a switched-capacitor regulator. The disclosed embodiments of the feedback system can simplify feedback design for the hybrid regulator that can include multiple converter stages. These disclosed embodiments can control the feedback to improve the efficiency of a hybrid regulator.
