Abstract
Current control device particularly for power circuits in MOS technology, which comprises a MOSFET transistor which has its source terminal connected to one terminal of a dissipative load, its gate terminal connected to a pump circuit which receives in input a supply voltage and a square-waveform voltage, and its drain terminal connected to a power supply. The device furthermore comprises a control circuit which is coupled to the MOSFET transistor by means of an electrical connection and generates signals for adjusting the supply voltage and the square-waveform voltage of the pump circuit.
