    Abstract: The present invention describes a device suitable for charging a 5 battery comprising at least a first (M10) and a second (M20) transistor. The transistors (M10, M20) are connected to an input voltage (Vin) and have output terminals; the output terminal of the first transistor (M10) is connected to the battery (LOAD). The device comprises a circuit (100) for driving the transistors (M10, M20) and said drive circuit (100) comprises 10 first means (CA1) suitable for regulating the current (Iout) in the battery during the charging phase of the battery (LOAD). The first means (CA1) are suitable for keeping the voltage on the output terminals of the transistors (M10, M20) the same during the charging phase of the battery (LOAD).

    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.
