The invention relates to a drive circuit for providing a drive signal (S3) for a switch in a switching converter in a manner dependent on a control signal (S2), the drive circuit comprising at least two groups (22, 30) of circuit components, each group having at least one circuit component, and the circuit components being coupled to one another and designed to provide the drive signal (S3) from the control signal (S2). In this case, voltage is supplied to the circuit components of the first group by means of the control signal, while voltage is supplied to the circuit components of the second group (30) by means of a supply voltage at a supply terminal (K2).
