Thanks

    Hi Gareth,

    Here are my comments on the SCH:

    • VIN caps are good, just make sure to put it as close as possible to the pin in the layout
    • Boost cap is good as well
    • For the inductor selection, they look good, just make sure the inductor saturation current rating must be greater than the peak current and the RMS or heating current rating must be greater than the RMS current.
    • The feedback resistors all look good I verified the math.
    • PG and VREG are good
    • For the EN pin, as you have is good, but you can also connect it to VIN and save the pull down resistor.

    Thanks!
