    Hi Jeff,

    Please note the following:

    • OUT (pin 12): recommended to use 2x47uF here. As I can't see where this goes/if it's included, please take this into consideration or ensure this. This recommendation and other information regarding this can be seen in section 9.2.2.1 on page 30 of the datasheet linked here.
    • CTL1/2/3: ensure that these are meeting the correct logic levels per your design.
    • Rest of the schematic should be fine.

    When doing the layout please follow the layout guidelines found in section 11.1 on page 33 of the datasheet linked earlier.

    Thanks,
    Field
