I'm in the process of building a lamp. It is about a Pendant lamp in which a coaxial cable with an outer braid is used for the power supply in order to swing the light objects (5 pendulums). In the light objects there are LEDs that require CC with 700mA. This connects the GND of all constant current sources in the canopy of the lamp. I am therefore looking for an LED driver (or an LED driver IC) that can handle common cathodes. The luminous objects should each have their own KSQ. Do you know something suitable? Maybe even a circuit diagram?
