Abstract
A current mode switching controller contains at least one controllable semiconductor switch, an impedance, a voltage divider, an external control circuit for regulating the voltage, and an internal control circuit coupled to the external control circuit and used to regulate the load current. The circuits controlling the controllable semiconductor switch according to the load current and the output potential. An integrator is provided for producing a control signal representing the load current as a result of time integration of the voltage. A signal is supplied to the internal control circuit as a control variable. Means for adapting the amplitude of the integrator contains at least one transconductance whose value in a transient state is inversely proportional to the output potential.
