    Manjunath,

    The schematic looks good to me. A few notes: 1) please choose the charge pump capacitor (C26, C27, C29, C30) voltage rating as high as possible, at least 10V, or even 16V; 2) in the layout please put the capacitors as close as to the pins; 3) in the layout please have solid power/ground connections to the device. Please let me know if you more questions in your application. Thanks for choosing TI parts.

    Regards,
    Hao
