Infineon REFICL5102U52WCCTOBO1, REF-ICL5102-U52W-CC LED Driver Evaluation Board for ICL5102, IPN60R600P7S for ICL5102

The Infineon REF-ICL5102-U52W-CC demonstrates a low-cost PFC+LCC LED driver for non-dimmable indoor lighting applications, where the LED current can be switched among three fixed levels. To reduce the system cost, the LCC is equipped with an open loop control and compact integrated LCC transformer. It used with feedforward mechanism, which LED current spread is narrow in this open loop control. The LCC is operated at high frequency so that the series inductance of the LCC topology can be integrated into the transformer. Both integrated LCC transformer and open-loop design result in a low system cost.
