Abstract: A pulse width modulation device includes a switching transistor for defining modulation phases, a capacitor, and switches arranged to: a) in a first phase, charge the capacitor to a voltage corresponding to the on/off threshold of the switching transistor, and b) in a second phase, connect the capacitor between a terminal for applying a setpoint voltage and the gate of the switching transistor. A constant current source is connected to apply a current in the capacitor tending to bring the gate of the switching transistor toward the on/off threshold.
