Abstract:
1. An integrated control circuit for a charge pump, said integrated circuit comprising: a first device suitable for regulating the output voltage of the charge pump; a second device for increasing the output voltage from the charge pump with a set ramp; and means for activating said first device and providing it with a first value of a supply signal in a first period of time and for activating said second device and for providing it with a second value of the supply signal that is greater than the first value in a second period of time after the first period of time, wherein the output voltage of the charge pump comprises a ramp ascending from a first value to a second value that is greater than the first value, and said second value is fixed by a reactivation of the first device, and wherein said second device comprises a capacitor coupled with the output voltage of the charge pump and with the terminal of a comparator having at the other terminal said reference voltage, said capacitor being charged by the supply signal.
