Dear All,
Would you tell us the spec of LM3409 package?
Please refer to the attached JPEG file.
Our customer needs to know length of "A" for their board design.
Best Regards,

Asai-san,
The LM3409 datasheet (http://www.ti.com/lit/ds/symlink/lm3409.pdf) includes the recommended LAND pattern for the 10-pin MSOP package. This is the information needed to complete the board design.
Best regards,
John
Asai-san,
To actually answer your question with a specific number. The "A" distance is 2.21875mm.
Best regards,
John
