ABSTRACT:
An integrated circuit has an on-chip supply voltage reducer, and includes a voltage converter for periodically charging the integrated circuit capacitance. The voltage converter may include a power switching transistor which is connected between an external supply terminal and an internal supply terminal and which is controled by a detector amplifier which senses the voltage across the integrated circuit capacitance connected to the internal supply terminal and which turns the switching transistor on and off depending on the value sensed, with a given hysteresis.
