Abstract: A battery charger operates in a current regulation mode and a voltage regulation mode. A value of the voltage on the battery being charged is sensed and compared against a target voltage value. The current regulation mode is active during charging while the sensed voltage is less than the target voltage value. When the sensed voltage reaches the target voltage value, the voltage regulation mode is enabled and the current regulation mode is inhibited.

Abstract: A battery charger includes an input supply terminal configured to receive a supply signal and a battery terminal configured to be connected to a battery. A supply switching circuit is arranged between the battery terminal and the input supply terminal. A control device generates a control signal to control operation of the supply switching circuit. A fuel gauge device provide a digital estimation of a voltage signal across the battery. A correction device modifies the control signal in response to the digital estimation of the voltage signal across the battery if that digital estimation is outside of a value range between two thresholds.

Abstract: A switching converter includes a first electronic switch and a second electronic switch and respective drive circuits for switching on and switching off alternatively the first and second electronic switches. The drive circuits have a supply line for supplying to them a supply voltage. At least one of the drive circuits has, coupled to it, a capacitor for storing the supply voltage. An electronic-switching circuit is provided for selectively disconnecting the drive circuit from the supply line when the electronic switch driven thereby is switched off. In this mode, the drive circuit is supplied by the voltage stored on the capacitor.
