Abstract

A multi-level switching converter circuit for converting a first voltage to a second voltage or convert the second voltage to the first voltage, includes: a power stage circuit and a control circuit. Through a valley current mode control, the conversion control circuit generates a first ramp signal to determine a first duty ratio of the first control signal, and generates a second ramp signal to determine a second duty ratio of the second control signal, thereby a switching node connected to one end of an inductor is switched between two of k levels of voltages, such that the first voltage or the second voltage is regulated to a predetermined target level, and a flying capacitor voltage across the flying capacitor is regulated and balanced at one (k−1)th of the first voltage.
