Hi Ti Team，

I currently have a module project that uses TAS2110. Help check if the schematic diagram is correct

    Hi,

    Sorry for the delayed response here.
    After further review of the schematic it is looking OK, just want to comment on the PVDD/VBST connection:

    • There seems to be only one decoupling capacitor, and it is rated for 16V. Recommendation is to select components so that derated capacitance due to DC voltage is not lower than 4uF at the specified boost voltage.
    • I assume your intention is to use external PVDD voltage, so VBST will not be used. Is this correct?
    • If using VBST to supply PVDD, it is recommended to place additional capacitance, close to each of the VBST and PVDD pins.
