The reason you (and many others) struggle to find a specific "LZC8650C" PDF is that these chips are often "House Numbers." Large lighting manufacturers often order chips from a foundry and ask them to print a custom model number on the casing so generic competitors cannot copy the BOM (Bill of Materials) easily.
