About MPM3833C's SW pins artworks

I am considering using MPM3833C and have confirmed the data sheet and sample circuit.
So I have a question,
Regarding the SW pin (5,6,7,15), 5,6,7 are tied on the board, but 15 seems to be floating.
Is it correct to recognize that this is connected internally and does not need to be connected externally?

Although it is connected in schematics, it does not seem to be tied on the sample circuit, so I asked you a question.
Thank you.

Hello rt9drivebaske,

Yes, the SW pin can be left floating.

Thank you,
