Abstract (en)
[origin: FR2864720A1] 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.
