Abstract
A control circuit for controlling a multi-level buck converter having N pairs of switches serially connected between an input terminal and a logic ground, wherein N is an integer equal to or greater than 2. The control circuit has a comparing circuit, a selecting circuit and a delay circuit. The comparing circuit compares a voltage feedback signal indicative of an output voltage signal of the multi-level buck converter with a reference signal to generate a comparing signal. The selecting circuit generates N set signals based on the comparing signal. The delay circuit delays the N set signals to provide N delay set signals to control the N pairs of switches when the output voltage signal falls in of an input voltage signal of the multi-level buck converter, of the input voltage signal, . . . , or of the input voltage signal, wherein k is a proportional coefficient.
