Abstract
There is provided a circuit arrangement for switching a current on and off without overcurrent. The circuit arrangement includes a current source, a load associated with the current source, a switching transistor for switching the current source on and off, where the switching transistor has a parasitic capacitance between a control electrode and a first output electrode, and a shorting device between the control electrode and the first output electrode of the switching transistor for switching off the current source. The current can be used, for example, to drive a laser diode.
