A method of controlling a pulse width modulated (PWM) voltage regulator including a control circuit of a power stage, and a circuit configured to determine a duration of charge phases and further configured to receive a charge signal and to generate a logic command may include controlling, using the control circuit, switches of the power stage as a function of the logic command at an end of a charge phase and at a start of a discharge phase of an output capacitance. The method may also include generating the charge signal to be one of enabled and disabled during charge phases and another of enabled and disabled during discharge phases, and delaying, at each PWM cycle, the logic command with respect to a previous PWM cycle to compensate at least one of a phase and a frequency difference between each PWM cycle and a reference clock signal.
