Hello,

Is it possible to get a schematic design review prior to layout? Loud high quality sound is important for us.

    Hi Jonathan,

    Please refer to our design guidelines: https://www.ti.com/lit/an/slaa988a/slaa988a.pdf

    Some comments about the schematic:

    • You may place the FB on every power supply before all decoupling capacitors, so that you can place all these caps close to each pin.
    • Add more decoupling capacitors for VBAT, note that individual decoupling is required close to SW inductor and close to VBAT pin. Higher priority on decoupling for SW inductor.
    • Replace 22uF on PVDD/VBST with 2x10uF, so that you can place one of them close to PVDD and one close to VBST.
    • Replace 0.01uF with 0.1uF on GREG, according to design guidelines.

    Let us know if there's any questions and if you get any updates on the design.

    Best regards,
