摘要: An integrated control circuit for a charge pump includes a first device for regulating the output voltage of the charge pump and a second device for increasing the output voltage from the charge pump with a set ramp. The integrated circuit includes 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 the second device and 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 in such a way that the output voltage of the charge pump ascends a ramp from a first value to a second value that is greater than the first value, the second value being fixed by reactivation of the first device.
