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.

Abstract: The switch mode power supply includes a switching cell SC controllable cyclically and including only one inductive element L and several individually selectable outputs. During each conduction cycle, a total power level corresponding to the sum of the individual power levels respectively required by all the outputs OUTi during this cycle is injected into the inductive element L, the outputs requiring a non-zero individual power level are selected successively and in a predetermined order that is identical for all the cycles, and, at each selected output, the corresponding individual power level is produced.

Abstract: A DC voltage converter produces an output voltage (VS) at an output terminal from an energy source. The DC voltage convert includes a selector switch includes a first input coupled to the energy source, a second input coupled to a ground, and an output coupled to a first terminal of an inductor. A second terminal is coupled to the output terminal of the converter and a capacitor is coupled between the output terminal and the ground. A regulator produces a control signal as a function of a result of a comparison of the output voltage with a reference voltage. A control circuit couples the output of the selector switch to the first or second input of the selector switch, as a function of the control signal. The converter may also include a means of inhibition adapted to inhibiting the control circuit when a current flowing in the inductor gets cancelled.
