    LC6685 based LED drivers

    I have 50 Chinese constant current isolated LED drivers based on LC6685 IC. 35 drivers are working fine, but there is a slight flickering in the rest of the drivers.
    I have checked the output with oscilloscope and found that there is a slight random voltage fluctuation.
    Is it possible to get the datasheet of LC6685 IC?
    Also highly appreciate if you could let me know what could go wrong.
