TPS62827: softstart datasheet spec question

Hello Hironori, 

Thank you for your question.

I would say that the main difference between TPS62827 and all other devices is the output capacitor.

Infect, if you refer to the LC matrices:

You can see that TPS62827 has a standard Cout of 3*10uF, whereas the other ones have a standard Cout of  2*10uF.

This difference is also visible in the EVM schematics of the respective products.

However, it could also be reasonable that the particular device implementation and operating mode leads to a slight difference in the Soft Start time.

Does this answer clarify your doubt?

If you have  any further questions, please ask me again.

Thanks,

Stefano
