Hi Prakash,

What product you are designing? For the system requirements, could you help to share some more details that 1)How many LEDs are cascaded? 2) How many channels need? 3) A integrated boost or BUCK converter need? 4) A digital interface like I2C need?

Hi Prakash,

No we do not have a device can support such input voltage range. Normally our device can only support up to 70V.
