Hybrid buck-boost dc-dc converter with flying capacitor

A hybrid buck-boost DC-DC converter with a flying capacitor, comprising:

• an input node configured to receive an input voltage from an input voltage source;
• a power inductor having a terminal connected to the input node and another terminal connected to a first switch node,
• wherein the flying capacitor has a terminal connected to the first switch node and another terminal connected to a second switch node;
• a first power switch coupled between the second switch node and ground;
• a second power switch coupled between the input node and the second switch node;
• a third power switch coupled between the first switch node and an output node;
• a fourth power switch coupled between the second switch node and the output node;
• and
• an output stage coupled to the output node, wherein the output stage comprises an output capacitor and a load resistor connected in parallel, and is configured to provide a load current based on an output voltage at the output node.
