LTC3766 and LTC3765 timing calibration

Category: Datasheet/Specs
Product Number: LTC3766,LTC3765

Hello,

There is a question on FGD resistor:

Do you suggest to pick value at minimum voltage and nominal power consumption(I have voltage trim 22-32V and dynamic load from 80% to 30% RF amplifier application) ?

What is the problem when SWB doesn't reach 0V  as I understand it can cause stress across FG transistor?

I attached example that at minimum DC SWB reaches 0 value and a little higher DC it 23V and more. 

Thank you.
