What voltage should be on the capacitor of the max660 chip?

Question

Electronics

I need to pick up capacitors for the MAX660 chip . I can't figure out what voltage.
Input voltage 5V. I get -5V

What voltage will be at the Cap + Cap- outputs? 5V or 10?
Inside it is like this:

Answer 1

5 volts
tobezh maximum voltage across C1, C2 equals Vin

Answer 2

capacitors are selected not for voltage, but for current for the required voltage for a particular consumer. in general, such converters have their drawbacks and it is not desirable to poke at random, it is better to install any microcircuit that supports the voltage inversion mode.
