Abstract
A voltage converter device converts an input signal having a given input voltage value into an output signal having an output voltage different from the input voltage. The device comprises a main module, arranged between an input terminal and a first circuit node, The device is adapted to output at the first circuit node a pulse-width-modulated signal switching between a first voltage value and a second voltage value, defining a switching range, by switching successively between a first mode of operation and a second mode of operation. The switching range of the pulse width modulation has an amplitude, calculated as the absolute difference between the first and the second voltage value, inferior or equal to half the input voltage.
