LMZ30604: Slow start interval accuracy

Part Number: LMZ30604

I have two questions at the LMZ30604 simple switcher:

One, Is the "slow-start interval" meaning a time to be output rising from 0% to 100% ?

Two, How expect the slow-start interval's accuracy will be?　What will be affected to the interval?

thanks,

Hi,
To answer your questions:
1.Yes.
2. There is not a guaranteed spec for the accuracy. It will affected by the tolerance of the current source and capacitor inside the module as well as the capacitor you put at the SS pin. In terms of the interval, it depends on the amount of capacitor at SS pin. Please refer to Table 8 in the datasheet.
