    Hello Amelia,

    The schematic diagram looks fine except for the output capacitors (C21/C23) were above the optimized of 10uF to 22uF. If the customer intend to retain the current value, then they need to verify the phase margin and it should be equal or greater than 45 deg.

    I cannot check the inductor current saturation (Isat) because the datasheet is not able in the web. Kindly ask customer to check the Isat and it should be higher than the ILIM indicated in the datasheet.

    Best regards,
