Hi Team,

I understand that the maximum voltage of SS pin is 0.51V(it is maximum voltage of VREF).

Is my understanding correct?

no. the VOUT follows SS voltage only when it is lower than 0.5V.
why ask this?

Hi Jasper-san,

Thank you for your prompt reply.

Our customer would like to know necessary voltage of soft start capacitor.

So, I understand that the voltage of SS pin does not become higher than 0.5V.

Is my understanding correct?

no. the voltage in the Css is equal to 5uA*Rss. Rss is the resistor in parallel with the Css.
