Q: TPS61093 Thermal Pad package information by 1294176

Can you please clarify the package thermal pad information in the TPS61093 datasheet.  It states that the SON 10-pin package (DSK) is the only choice.

On pages 4 and 14, the package illustrations show a non-square thermal pad (e.g. there are two little 'wings' out the square portion to either side).

But, in the package mechanical drawing info at the end of the data sheet (3 pages following Pack Materials page 2), the thermal pad is square in the package dimension drawing (1st page), the thermal pad dimension drawing (2nd page), and the land pattern drawing (3rd page). E.g - no 'wings'.

 

So, which is correct?

I spoke with a member of the packaging team and he said that the two tabs on top and bottom are present on the package. This is how the devices connect to one another on the lead frame.

As far as layout, he recommends that the customer follow the mechanical diagram on pages 20 and 21. You should not try to layout and solder the tabs. The device will sit on top of the power pad solder so the tabs won't be in direct contact with the board.
