LP1K5C18: 1500W UV-LED driver for industrial use

This driver was developed in cooperation with manufacturers of UV-exposure lamps. The goal was to drive every UV-LED with a well defined current and still keep a low voltage system (<60 Volts). Therefore we used the, in 2010 by our R&D team introduced, multi-channel topology. All 18 channels are sensed for possible failures of a single UV-LED, so as to avoid non-homogenic exposure of the subject in case.
