A circuit system having a voltage converter having an input path, an output path, and having a plurality of phases, each phase having at least one half-bridge and at least one fuse, each branch of the half-bridge having a respective MOSFET. The circuit system recognizes a defective MOSFET and controls the MOSFETs of the intact phases in such a way that a sufficiently large current trips the fuse connected in series with the defective MOSFET in order to enable an emergency operation of the voltage converter. A method for operating such a circuit system is also described.
