TAS5711PHPEVM: alternative inductor

Paul Antunes
Intellectual 2550 points

Part Number: TAS5711PHPEVM

dear audio team,

one TI key account is building a demo using TAS5711 evm as reference design.

it looks like some parts are discontinued such as inductors L1-L4 (#A7503AY-220M).

Do you have alternative inductor to recommend ? ABC, Sunlord and Wurth are preferred suppliers.

thank you in advance for your support.

regards,

Paul

    Hi Paul,
    Toko A7503AY-220M inductors are used in TAS5711 EVM design. This inductor is 22uH with 20% tolerance, and the maximum rated current is 2.7A. You can design your output filter with this tool to determine how much inductance is needed in your application www.ti.com/.../slaa701a.pdf www.ti.com/.../slac729
    Then calculate the maximun output current on the inductors according to the maximum output power and the speaker resistance. Make sure there is enough margin to the maximun rated current. The efficiency is higher with lower DC resistance in the inductors.
    ABC, Sunlord and Wurth inductors are widely used by our customers, you could choose the approriate ones for your application.
    Best regards,
    Shawn Zheng
