TAS6424L-Q1: Is it okay to use chip inductor instead of power inductor on the output?

Part Number: TAS6424L-Q1

Tool/software:

Dear TI experts,

My customer wants to use chip inductor instead of power inductor on the output.

Could you conform that it is okay?

They want to change L4012 and L4014 to chip inductor.

They saw the document SLOA242, there are some results using chip inductor.

Please check this issue. Thanks.

Best regards,

  • Chase,

    The Murata DFE322520FD-3R3M is a good choice.  Contact Murata and see if they have upgraded this part.  I believe that have one with a "T" in the suffix for this amplifier.  Many other companies make size too.  The Coilmaster below the Murata is the same size and is good also.
