    Hi Eric,

    The LM5121 can support LED applications. Can you please provide your application parameters? {VIN Range, VOUT, IOUT}. The LM5122 is also a good alternative to the LM5121. There are currently some reference designs using the LM5122 in and LED application. The TPS40211 is also a good selection for LED applications.

    To find existing reference designs please look at TI reference design website.

    Please feel free to contact me directly.

    Thanks,

    Garrett
