    Hi Shyam,

    The schematic looks good.

    Comments for layout:

    1. No need to use traces on the power pin but directly to cover the pins with polygon. Such as VIN pin, input caps, CP, SW, output caps.

    2. Because Cvaux carries the peak currents of the gate control block, it should have a compact and direct routing to the VAUX and GND pin 10, staying away from sensitive signals but not directly connect to ground copper. Please see below example for GND pin and VAUX pin connection.
