Abstract: A DC-DC converter including: a switch, having a control terminal receiving a control signal, and a conduction terminal supplying a current; a load, coupled to the conduction terminal of the switch and selectively receiving the current; a control circuit, receiving a clock signal and generating the control signal in synchronism with the clock signal; an overcurrent sensor, coupled to the switch so as to monitor an electrical quantity correlated to the current and to output a protection signal in presence of overcurrent; moreover including overcurrent-protection circuitry, receiving the protection signal and the clock signal and generating a disabling signal for the control circuit if delay between an overcurrent detection and the clock signal is shorter than a detection time.

Abstract: A device and method for driving a converter circuit that supplies a charge via a first electronic switch and a second electronic switch alternately turned on and off. A generator module generates a memory signal, indicating the duration of a first dead-time interval. A delay module, sensitive to the memory signal controls turning-on of the first electronic switch with a delay, with respect to turning-off of the second electronic switch, so that a second dead-time interval has a duration substantially equal to the duration of the first dead-time interval.

Abstract: An apparatus adapted to convert an input analog signal to an output digital signal includes means adapted to convert a first digital value of the output signal of the apparatus to a first analog value (IN1), wherein the first digital value is emitted by the apparatus at a first time instant, and also means for feeding back the first analog value to the input of the apparatus. The apparatus includes first means adapted to determine the difference between the first analog value and a second analog value (IN) of the input signal at a second time instant successive to the first time instant. The apparatus also includes second means adapted to convert the difference to a digital value and third means adapted to add or subtract the digital value of the difference to or from said first digital value by obtaining the output digital signal.
