There is described a device for converting an input signal having a given input voltage (Vbat) value (Vbat) into an output signal having an output voltage (Vout) (Vout) different from the input voltage (Vbat). The device comprises a main module (56), arranged between an input terminal (54) and a first circuit node (N1 ), The device is adapted to output at the first circuit node (N1 ) a pulse-width- modulated (PWM) signal switching between a first voltage value and a second voltage value, defining a switching range (SR(i)), by switching successively between a first mode of operation and a second mode of operation. The switching range (SR(i)) of the pulse width modulation (PWM) has an amplitude, calculated as the absolute difference between the first and the second voltage value, inferior or equal to half the input voltage (Vbat). |
