摘要： A frequency translator is usable in a switching DC-DC converter of the type operating as a voltage regulator and as a battery charger. The frequency translator receives at inputs a division voltage (VFB) proportional to a present value of the output voltage (VOUT) of the DC-DC converter, 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, and supplies at an output a bias current (IBIAS) which is supplied to an input of an oscillator 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 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 is operating in the current limitation condition.

摘要： A charge pump MOS voltage booster has reduced voltage drops and ripple. This voltage booster is advantageously used in two applications. The voltage has four MOS transistors instead of diodes in a classical voltage booster, which exhibit an undesired voltage drop. The voltage booster also has an oscillator with two outputs and two corresponding charge transfer capacitors. In this manner, the undesired voltage drops and ripple are reduced without complicating the circuitry structure.
