    Hello

    I don't see anything outstanding in the design.

    Here are my comments:

    1. It appears that the RT resistor is not used; open = 500kHz

    2. Your output capacitance is a little small, but should be OK.  You may want to leave space on the PCB for another output

    cap to improve transient response.

    3. You may want to leave room on the PCB layout for a feed-forward capacitor across the upper feed-back resistor; if needed.

    4. Be sure that the inductor is rated for at least the typical value of the high-side current limit.

    5. Be sure to follow the data sheet PCB layout suggestions.

    Thanks
