TPS27S100: Incorrect dimension for WQFN thermal pad

Peter Arnold33

Part Number: TPS27S100

The thermal pad drawing on the data sheet page titled RRK0016A Package Outline appears incorrect. It gives the width as 2.05mm and the length as 0.21mm. It looks like that should be 2.1mm. Can you please confirm this for me? Our librarians will not build a part symbol without a corrected diagram or confirmation of dimensions.

Hi Peter,

2.05mm is correct https://www.ti.com/lit/ml/mpqf550/mpqf550.pdf. We will double check and get back to you!

BR, Rakesh

Thank you Rakesh. Just to be clear, 2.05mm is not in question. The problem dimension is the 0.21mm, which I think should be 2.1mm. Please check that number.

Hello Peter,

I am working with the product engineering team to get this corrected in the datasheet right now. The stencil below is correct and specifies the parameter to be 2.55mm. In any case the 0.21mm is a misprint and I will have official guidance here shortly.

Thank you Timothy.

Please let me know the correct number that should appear instead of 0.21mm, as soon as you have it. The corrected drawing can come later.

Best regards,

Hello Peter,

After talking with the verification/packaging team I can confirm that the 0.21mm parameter should be 2.55mm (not 0.21mm or 2.1mm).

I will take the necessary steps to drive a datasheet change. Thank you for pointing this out.
