Abstract

Ein Spannungswandler (10) umfasst eine Induktivität (11), einen ersten und einen zweiten Schalter (15, 16) und eine Steuereinheit (25). Einem ersten Anschluss (12) der Induktivität wird eine Eingangsspannung (VIN) zugeführt. Der erste Schalter (15) ist zwischen einem zweiten Anschluss (13) der Induktivität (11) und einem Bezugspotentialanschluss (17) angeordnet. Der zweite Schalter (16) ist zwischen dem zweiten Anschluss (13) der Induktivität (11) und einem Ausgang (19) des Spannungswandlers (10) angeordnet. Die Steuereinheit (25) ist ausgelegt, den ersten Schalter (15) in einer ersten und einer zweiten Phase (A, B) einer ersten Betriebsart des Spannungswandlers (10) in einen sperrenden Betriebszustand sowie den zweiten Schalter (16) in der ersten Phase (A) in einen leitenden Betriebszustand und in der zweiten Phase (B) in einen Betriebszustand mit einer anderen Leitfähigkeit einzustellen.
