Abstract: A charge pump generates an output voltage. A first circuit generates a pulse width-modulated signal as a function of a deviation between the output voltage and a setpoint voltage. A second circuit receives a periodic signal and conditions the supply of the periodic signal to a control input of the charge pump as a function of the state of the pulse width-modulated signal.
