I've highlighted the voltage divider on the LTC3106 solar harvester example:
The datasheet explains that the RUN
pin is connected to a comparator which enables a certain function of the IC for 0.4 or 0.6V:
Questions:
How did they get the relations between \$V_{in}\$ and \$V_{RUN}\$? Are there some assumptions made on the current going into the IC?
The ratio R1/R2 can be achieved by different resistor values. 3MOhm/3Mohm = 3KOhm/3Kohm. What should one take into account when choosing the values?
