摘要:A charge pump voltage booster circuit with control feedback of the typecomprising an output line connected to a load and on which is produced an outputvoltage boosted in relation to a supply voltage and a feedback loop incorporating acharge pump connected to said line and a control logic circuit of said pump interlockedwith a comparator having an input connected to the line comprises also an auxiliarycharge pump connected in turn to said line and designed to supply a quantity of currentgreater than or equal to the leakage currents of the load in stand-by condition. Theauxiliary 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 maincharge pump for a brief time period sufficient to take the booster output to a sufficientvalue.
