ABSTRACT:
A DC-DC converter includes a switching transistor coupled to output terminals via an inductor and a rectifier. The converter also includes a circuit for sensing whether a current change in the main current path of the switching transistor reaches a given value subsequent to an initial current rise, if any, at the start of a conduction period. A control circuit is responsive to said sensing circuit to remove the drive to the switching transistor if said given value is reached.
