Abstract

A voltage regulation system, particularly for a motor vehicle, adapted to be connected to a voltage source in order to provide a regulated voltage Vdd to at least one functional component F, the regulation system including a pre-regulator adapted to be connected to a voltage source and a regulator REG including at least one pre-regulation port PPR adapted to be connected to the pre-regulator and one functional port Pdd adapted to be connected to a functional component, the regulator including an adaptation device Q directly connecting the pre-regulation port to the functional port of the regulator, the adaptation device consisting of a single MOS power transistor including a drain D, a source S and a gate G. The MOS transistor includes an intrinsic diode DIODE between its drain and its source which is oriented to block the flow of a current between the functional port and the pre-regulation port.

Dependent claims

A voltage regulation system (1), adapted for being connected to a voltage source (BAT) of a motor vehicle, in order to provide a regulated voltage (Vdd) to at least one functional component (F), the regulation system comprising:

a pre-regulator (PR) adapted for being connected to a voltage source (BAT);
and
a regulator (REG) comprising at least one pre-regulation port (PPR) adapted for being connected to said pre-regulator (PR) and one functional port (Pdd) adapted for being connected to the at least one functional component (F) of the motor vehicle,
said regulator (REG) comprising an adaptation device (Q) directly connecting said pre-regulation port (PPR) to said functional port (Pdd) of said regulator (REG),
said adaptation device (Q) comprising a single MOS power transistor including a drain (D), a source (S) and a gate;
wherein said single MOS transistor comprises an intrinsic diode (DIODE) between said drain (D) and said source (S) which is oriented so as to block a flow of a current between said functional port (Pdd) and said pre-regulation port (PPR),
wherein said functional port (Pdd) of said regulator (REG) is adapted for receiving a functional voltage Vdd, and said pre-regulator (PR) is configured for providing said pre-regulation port (PPR) with a pre-regulation voltage VPR so that:
VPR <Vdd +Vdiode.
