Abstract
A method of feedback controls a switched regulator generating a regulated voltage on an output terminal and being driven by a pulse width modulated (PWM) signal that determines on-phases during which the output terminal is selectively connected to a supply line, and off-phases during which the output terminal is disconnected according to a pulse skipping mode. The method may include comparing the regulated voltage with a reference voltage, and during the on-phase of the PWM signal, selectively connecting or disconnecting the supply line to the output terminal based upon the comparing for keeping the regulated voltage constant. The method may also include incrementing, decrementing, or leaving unchanged a duty-cycle of the PWM signal at every PWM cycle also based upon the comparing.
