TAS5805M: Need Efficiency Data of the TAS5805 for 19V PVCC, 4ohm Load

Wayne Chen (Audio AE)

Part Number: TAS5805M
Other Parts Discussed in Thread: TAS5805

Hi Sirs,

As title, would you please advise the efficiency chart of the TAS5805 based on the test condition of 19V PVCC, 4ohm load?
The TAS5805 datasheet specifies efficiency data up to 12V only.

Thank you and Best regards,

Hi Wayne,

We are connecting to the right team mate to solve this issue. As some team mates are on National holiday in China, reply may be delayed. Thanks for the understanding!

Hi Wayne,

Do you want the switching frequency to be 768kHz, 1SPW Modulation, both channels on, and 4.7uH +0.68uF LC filter? The more details you share with us the better we can give you more relevant information for your system.

Best Regards,

Robert Clifton
