1. A circuit for controlling a battery-charger device with a closed-loop architecture, the circuit comprising:

  • sensing means for sensing an operative quantity of the device;

    control means for alternately controlling the sensing means to track the operative quantity during a tracking phase and to hold the operative quantity during a holding phase; and

    driving means for providing a regulation signal that regulates the operative quantity based on a comparison between the operative quantity sensed by the sensing means and a reference value, wherein the control means causes the driving means to hold the regulation signal during at least part of each of the holding phases.
