摘要
A buck converter includes an output stage, a FCVB control circuit and a driver. The output stage includes a plurality of switches and a flying capacitor, wherein the switches are connected in series, the flying capacitor is coupled between two of the switches, and the output stage is configured to receive an input voltage to generate an output voltage. The FCVB control circuit is configured to compare a voltage of the flying capacitor with half of the input voltage to generate a comparison result, and the FCVB control circuit further responds to the comparison result to generate a first control signal and a second control signal based on a first PWM signal and a second PWM signal. The driver is configured to generate a plurality of diving signals according to the first control signal and the second control signal, wherein the driving signals are arranged to control the switches, respectively.
