Power up Ramp

[bettinawyss]

Hi, 

I would like to use PF8200 together with PolarFire FPGA in a project. However, I noticed that the power ramp up times are slightly outside the specifications of PolarFire (200us). Is there a way to somehow get longer ramp up times? 

Thank you in advance

Yes exactly. E.g: the start up ramp of the voltage regulator output should take at least 200us to go from 0 to 1V.

For the slew rate time which can't modify for the output regulators.

Do you mean the start up time?do you need longer than 200us of PMIC?
