Abstract: An apparatus adapted to convert an input analog signal (In) to an output digital signal (OUT) is described. The apparatus comprises means (1) adapted to convert a first digital value (d(IN1)) of the output signal of the apparatus (100) to a first analog value (IN1), said first digital value (d(IN1)) being emitted by the apparatus at a first time instant, and means for feeding back the first analog value (IN1) to the input of the apparatus. The apparatus (100) comprises first means (2, 3) adapted to determine the difference (Diff) between the first analog value (IN1) and a second analog value (IN) of the input signal of the apparatus at a second time instant successive to the first time instant, second means (4) adapted to convert said difference (Diff) to a digital value (d(Diff)) and third means (5) adapted to add or subtract said digital value (d(Diff)) of said difference to or from said first digital value (d(IN1)) by obtaining said output digital signal (OUT).

Abstract: The frequency translator (72) is usable in a switching DC-DC converter of the type operating as a voltage regulator and as a battery charger. The frequency translator (72) receives at inputs a division voltage (VFB) proportional to a present value of the output voltage (VOUT) of the DC-DC converter (70), a reference voltage (VREF) correlated to a nominal value of the output voltage (VOUT), and a limiting signal (VL) indicative of a normal operation or of current limitation operation of the DC-DC converter (70), and supplies at an output (72u) a bias current (IBIAS) which is supplied to an input of an oscillator (32) supplying at an output a comparison signal (VC) presenting a periodic pattern with a frequency which is correlated to the bias current (IBIAS). In particular, the frequency translator (72) operates in a way such as to regulate a frequency translation of the comparison signal (VC) as a function of the difference between the division voltage (VFB) and the reference voltage (VREF) only when the DC-DC converter (70) is operating in the current limitation condition.

Abstract: The method of a protection circuit includes a reference voltage source and at least one circuit which are connected together via a switch. A memory element is connected to the input of the circuit, downstream of the switch. The switch is temporarily opened by a control signal generated by a monostable circuit when detecting switching of power elements belonging to an electronic device embedding the protection circuit. When the switch is open, the memory element supplies the circuit with the reference voltage previously stored. In this way, switching of the power element that might cause noise on the reference voltage cannot disturb the circuit and thereby cannot cause a faulty operation of the latter.
