ABSTRACT:
A charge pump voltage booster circuit with control feedback of the type comprising an output line connected to a load and on which is produced an output voltage boosted in relation to a supply voltage and a feedback loop incorporating a charge pump connected to said line and a control logic circuit of said pump interlocked with a comparator having an input connected to the line comprises also an auxiliary charge pump connected in turn to said line and designed to supply a quantity of current greater than or equal to the leakage currents of the load in stand-by condition. The auxiliary pump has current consumption much lower than that of the main charge pump. In addition, upon emerging from the off state there is provided starting of the main charge pump for a brief time period sufficient to take the booster output to a sufficient value.
