Hello,

I would like to use ADP5301ACBZ-2-R7, Option 0 without output discharge. But I would like to use a 1.1v or 1.0v output. This output value is only available in Option 1.

Is it still possible to make a resistor divider outside the VID pad in order to have the correct output value (1.1v or 1.0v) ? In this case what will be the value of the external resistors ?

With Option 0 without output discharge, the soft startup time is 350us. If I want to lower this value, does it help to keep the external capacitor precharged ? In ideal case where the output capacitor is already precharged at the requested output voltage, what is the startup time ?

Any help would be appreciated

it's not possible to get 1.1V or 1.0V on the option 0 model. ADP5300ACPZ-3-R7 can meet your requirement.

in terms of start up time, the time depends on internal reference ramp up time so there is same start up time even you use a precharge capacitor.

Thanks!
