LM3410: LM3410 maximum LED current only 50mA

Part Number: LM3410

Hi Our design with LM341O LCD back light driver supports only 50 mA . We actually need 290 mA . The current set resistor can influence this . Please let me know. I have added the section of schematic.

    Hello Prashob,

    That schematic is very hard to read, I can't tell for sure what the values are. Do you have a clearer version? Would you also be able to provide a BOM? I cannot tell what the current sense resistor value is in your schematic or what the inductor current rating is.

    Also, what is the input voltage? Have you verified that it is not drooping when the LM3410 is enabled? Thanks.

    Regards,

    Clint
