  • Hi,

    I'll check it and give you feedback tomorrow.

    Thanks,

  • Hi,

    Sorry for response delay due to some other urgent support cases.

    My comments for the schematic:

    1. Recommend to change C519 from 1uF to 4.7uF according to the recommendation on datasheet.

    2. Recommend to add a 1uF cap between V5DRV and PGND.

    3. It's strange that customer uses a 11A inductor with 18A saturation current  and marked 22A for the rail. Please double check the inductor chosen here.

    4. Since the I don't know whether the current rating and OCP is incorrectly marked on the schematic, I didn't check the OCP setting resistor. But that's easy to check with equation on datasheet.

    Thanks,

    Andrew
