    Hello

    The design calls for a 470uH inductor.  The 47uH inductor should work, but the device

    will be operating in the DCM mode.  That means you would have somewhat larger output voltage ripple.

    Ensure that your input and output capacitors are selected according to the data sheet recommendations.

    Please follow the PCB layout recommendations in the data sheet as closely as possible.

    Thanks
