TPA3113D2: Need TPA3113 Efficiency with 20V PVDD

Part Number: TPA3113D2


Hi Sirs,

Would you pls advise the TPA3113 efficiency plots with 20V PVCC and 4ohm BTL load? Current datasheet offers 12V's efficiency chart.



Thank you and Best regards,

    Hi Wayne,
    This application is very rare and we don't have the data for this case. Can't understand why customer use so low load resistance and so high PVCC voltage for TPA3113D2. This device only supports low output power, users should use higher resistance speaker and lower PVCC voltage if they really care about efficiency.
    Bet regards,
