The multi-level voltage circuit includes a first switch path, a second switch path, and a third switch path each having a respective on-resistance and coupled in parallel between an input node and an output node.

By activating at least two of the three switch paths to generate the low-frequency voltage, it may be possible to reduce an equivalent resistance of the multi-level voltage circuit, thus helping to improve efficiency and reduce power loss of the MCP circuit.
