Abstract
A hybrid single-mode buck-boost converter is disclosed. The hybrid single-mode buck-boost converter comprises: an inductor having a first terminal connected to the input voltage (VIN) and a second terminal connected to an intermediate node (Vx); a switched-capacitor network circuit connected to the inductor through the intermediate node (Vx) and configured to perform switching operations to maintain a voltage at the intermediate node at a specified ratio of the output voltage of the buck-boost converter; and an output capacitor connected to the switched-capacitor network circuit through an output node.
Claims6
A hybrid single mode buck boost converter comprising:
- an inductor having one end connected to an input voltage(VIN) and another end connected to an intermediate node (Vx);
- a switched-capacitor network circuit coupled to the inductor through the intermediate node (Vx) and configured to perform switching operations to maintain a voltage at the intermediate node at a specific ratio of an output voltage of the buck-boost converter;
- and
- an output capacitor connected to the switched-capacitor network circuit through an output node.
