Voltage regulator

A voltage regulator, comprising:

• a) an input port with two terminals, and being configured to receive an input voltage;
• b) an output port with two terminals, and being configured to generate an output voltage, wherein the input port and the output port have a common ground potential;
• c) at least one group of input switches coupled in series between the two terminals of the input port, wherein a common node of every two adjacent input switches in each group that form an input half-bridge topology is taken as an input switch node;
• d) at least one output half-bridge topology coupled between two terminals of the output port, wherein a common node of a high-side output switch and a low-side output switch in each output half-bridge topology is taken as an output switch node;
• and
• e) a plurality of storage capacitors, wherein each of the storage capacitors is coupled between one input switch node and one output switch node, such that each path from the input port to the output port comprises at least one storage capacitor.
