Abstract: A DC-DC boost converter (11) includes an inductor (L) coupled between an input voltage (Vin) and an input node (Nn), a first path coupled between the input node (Nn) and a first output node (N1) at which a first output voltage (VBOOSTL) is generated, and a second path coupled between the input node (Nn) and a second output node (N2) at which a second output voltage (VBOOSTR) is generated. The DC-DC boost converter (11) operates in a first operating phase where the first path boosts the first output voltage (VBOOSTL) and where the second path is kept from boosting the second output voltage (VBOOSTR) by the second path being coupled to the first path, and operates in a second operating phase where the second path boosts the second output voltage (VBOOSTR) and where the first path is kept from boosting the first output voltage (VBOOSTL) by the second path not being coupled to the first path.
