An electronic device and a driving circuit are provided. The driving circuit includes a first driving signal generator, a first voltage conversion circuit and a first switch. The first driving signal generator generates a first driving signal according a first input signal, wherein the first driving signal is a pulse width modulated signal. The first voltage conversion circuit is coupled between the first driving signal generator and a control terminal of a first power transistor, converts the first driving signal to an output driving signal by charges a capacitor and discharges the capacitor, wherein the output driving signal is output to the control terminal of the first power transistor. The first switch is couple with the first power transistor in series, and is controlled by a control signal to be turned-on or cut-off.
