Patent ID: 7319308

Claim:
A DC/DC converter, comprising: an output terminal; a first switch coupled to an input voltage and to a reference voltage, said first switch having a terminal and being suitable for driving a load connected to the output terminal of said DC/DC converter; a first inductor having an intrinsic resistance and being connected to the terminal of said first switch; a control circuit suitable for generating a driving signal of said first switch at a switching pulse, said control circuit having a first input terminal connected to the output terminal of said DC/DC converter; a first resistive element and a first capacitor connected between said terminal of said first switch and said reference voltage, the first resistive element and first capacitor being connected to one another at a common terminal and having a resistance and a capacitance, respectively, that are sized such that an inverse of a product of said resistance and capacitance are lower than an angular frequency of said switching pulse and are higher than a ratio of the intrinsic resistance to inductance of the first inductor, said control circuit having a second input terminal coupled with the common terminal of the first capacitor and of the first resistive element.
