  • Battery-charger device with improved stability
    Patent number: 7692406
    Abstract: A circuit is provided for controlling a battery-charger device with a closed-loop architecture. The circuit includes sensing means for sensing an operative quantity of the device, control means, and driving means. The control means alternately controls the sensing means to track the operative quantity during a tracking phase and to hold the operative quantity during a holding phase. The driving means provides 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. The control means causes the driving means to hold the regulation signal during at least part of each of the holding phases. Also provided is a method of controlling a battery-charger device with a closed-loop architecture.
