Are application notes and/or design examples for this topology of using the LYT2002 available?
In the datasheet (page 2 - refer to attachment) there is this toplogy described.
Brief user requirements for this topology would be:
Vin = 150...200 Vdc
Vout (LED string voltage) = 310Vdc
Iout (LED-current) = 15mA
mode = CCM if possible else MDCM
