Abstract: The circuit has a transistor switch (4) with a reverse input logic between an inductor (L) and a connection terminal of a load (3). A gate of the switch is coupled to a supply voltage of the inductor or to a voltage less than a source voltage (6) of the switch at the inductor side. A selection circuit selects the higher voltage between the supply voltages of the inductor and the switch. Independent claims are also included for the following: (A) a process for protecting a voltage-up converter (B) a voltage-up converter including a protection circuit.

Abstract: The circuit has a high voltage N channel MOS transistor (31), whose gate receives a control signal referred to a reference voltage (G) and source is connected to the voltage. A base of a high voltage PNP transistor (32) is connected to a drain of the MOS transistor and an emitter of the PNP transistor receives a supply voltage. A collector of the PNP transistor supplies a voltage to a control terminal of a high voltage switch.
