Circuits comprising: a first capacitor(C1); a first switch(S1) having a first side coupled to a VIN and a second side coupled to a first side of C1; a second switch(S2) having a first side coupled to the second side of S1; a third switch(S3) having a first side coupled to a second side of S2 and a second side coupled to a second side of C1; a fourth switch(S4) having a first side coupled to a second side of S3 and a second side coupled to a V, wherein: in a first state, S1 and S3 are off, and S2 and S4 are on; in a second state, S1 and S3 are on, and S2 and S4 are off; and at least one of a control of S1, a control of S2, a control of S3, and a control of S4 is coupled to a time-varying-slew-rate signal.

Circuits and methods for slew rate control of switched capacitor regulators

An inductor; a first switch having a first side connected to a first voltage source (VS); a second switch having a first side connected to a second side of the first switch (SS), and a second side connected to a first side of the inductor (SI); a third switch having a first side connected to theSI; a fourth switch having a first side connected to a second side of the third switch (SS), and a second side connected to a second voltage source (VS); a fifth switch having a first side connected to theSI, and a second side connected to the VSand/or the VS; a first capacitor having a first side connected to theSS, and a second side connected to theSS; and a second capacitor having a first side connected to a second side of the inductor, and a second side connected to the VS

Circuits for three-level buck regulators

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.
