Abstract
In one embodiment an Inductive buck-boost-converter has an input (In) to which an input voltage (Vin) is supplied, an output (Out) at which an output voltage (Vout) is provided as a function of the input voltage (Vin), an inductor (L) having a first and a second terminal (Lx, Lx), a first switch (A) which switchably connects the inductor's (L) first terminal (Lx) to the input (In), a second switch (B) which switchably connects the inductor's (L) first terminal (Lx) to a ground potential terminal (), a third switch (C) which switchably connects the inductor's (L) second terminal (Lx) to the ground potential terminal (), a fourth switch (D) which switchably connects the inductor's (L) second terminal (Lx) to the output (Out), and a control unit (CTL) coupled to respective control inputs of first, second, third and fourth switches (A, B, C, D). Therein the converter is operated in three phases () by the control unit (CTL). In one of these three phases a transistor realizing the fourth switch (D) is driven in its saturation region by the control unit (CTL).
