    Hi Aswathy,

    1. Please make sure the input voltage is higher than 2.97V otherwise the controller will not operate.

    2. With the 226kohm R39, the frequency will be lower than 100kHz. It may still work but TI does not guarantee its performance as it is out of the range in the datasheet.

    3. Please confirm if you would like to go with the low frequency or willing to change. And then I will help review the other parts.

    Thanks,
    Yinsong
