Abstract (en)
[origin: EP1235465A2] The driver circuit and controller are remote from the load, which can only be operated within a defined operating voltage interval. The driver circuit has a controllable current source (T1) driven by a regulating element (T2,T3) with a first input (18) from a defined reference voltage (VCC) and a second input (19) for feeding the regulating voltage for the load (8,31).
