Claim 0:
1. An integrated laser driver circuit for switching a pulse current (IP) for a laser diode, the integrated laser driver circuit comprising:
a plurality of sub-switching units, each generating a partial current (IT) and including a switch that pulses the partial current (IT), wherein the sub-switching units of the plurality of sub-switching units are connected to one another in parallel for generating a pulse current (IP); and
an energy accumulator integrated into each of the sub-switching units to provide switching energy required for switching the switch, wherein each sub-switching unit comprises a local supply terminal for applying a supply voltage and a local ground terminal, wherein the energy accumulator is connected between the supply terminal and the ground terminal, and wherein the energy accumulator is a capacitor wherein each sub-switching unit comprises a current source in the form of a transistor, which is switchable via the switch, for generating the partial current (IT) and wherein each sub-switching unit comprises a reference input connected to the current source for setting the partial current (IT).
