Hi,

Could you tell me about TPS53353 mode settings.
Customer does not need a SS function.

For that reason,Customer is trying to install a 0Ω resistor.
Can we set up a resistance that has not been written in the data sheet?

In that case,Is it correct in the idea that the soft-start time = 0?

TPS53353 is a new part for our team. So far as I know, you cannot deviate from the recommended values. You cannot have a 0 soft start time. That would require infinite current. I would recommend they just use the minimum time of 0.7 msec.
