Abstract
In one embodiment, a voltage converter comprises a step-down converter (DC), to which can be supplied, on the inlet side, an inlet voltage (VBat), to which is supplied, on the inlet side, a control voltage (Vs), and which has an outlet () to make available a first outlet voltage (V), as a function of the inlet voltage (VBat) and the control voltage (Vs), a charge pump (CP), coupled with the step-down converter (DC) on its outlet (), with an outlet () to make available a second outlet voltage (V), as a function of the inlet voltage (VBat) and the first outlet voltage (V), and a voltage regulator (Ctl), to which a first effective voltage (Vb), as a function of the first outlet voltage (V), and a second effective voltage (Vr), as a function of the second outlet voltage (V), are supplied, and which has an outlet to make available the control voltage (Vs), as a function of the first and the second effective voltages (Vb, Vr). Moreover, a method for voltage conversion is disclosed.
