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.
