Abstract
The invention proposes a voltage regulating device having a switch in an electrical circuit between a first node () and a second node (), comprising a first field effect transistor () and a second field effect transistor () connected in cascade. The switch is controlled by: —setting the gate (G,G) of the first transistor to a first electrical potential, and, —to close the switch, setting the gate (G, G) of the second transistor to the first potential, or —to open the switch, setting the gate of the second transistor to the electrical potential of the second node, with the difference between the first potential and the second potential then being adapted to allow opening the first transistor and the second transistor. The switch can be used in a switched-mode power supply.
