The driving circuit includes a first bootstrap capacitor provided a first bootstrap voltage to drive the corresponding switch, and a second bootstrap capacitor provided a second bootstrap voltage to drive the corresponding switch. When converter operates in buck mode and the first or second bootstrap voltage is smaller than a threshold, the driving circuit generates current signals to respectively charge the first and second bootstrap capacitors based on an input voltage, and the first and second bootstrap voltages.
