  • DC/DC converter
    Patent number: 7084611
    Abstract: The invention relates to a DC/DC converter including an input to which an input voltage Vin is applied, a inductance L whose one terminal is connected to the input, a first controllable switch N1 via which the other terminal of the inductance is connectable to a reference potential Vss, a second controllable switch P1 via which the other terminal of the inductance is connectable to the output of the converter, and a regulator circuit 1 configured so that it is able to control the two switches in regulating the output voltage of the DC/DC converter to a predetermined wanted value. The second controllable switch is a PMOS-FET.
