Abstract
Circuit arrangement for switching an inductive load, for example in clocked voltage regulators, includes a switching transistor which is operated in a high-side circuit and is connected to a free-running transistor in a half-bridge arrangement, with the inductive load to be switched positioned in a node between the switching transistor and the free-running transistor. The circuit arrangement also includes a driving circuit for the switching transistor. The switching transistor is connected to an auxiliary transistor in a current balancing arrangement, and the current balancing mode of the transistors can be controlled as a function of a potential present in the node.
