Will Isosceles Boost survive a 12V power supply?

[rockmonolit]

Hello everyone.
Could someone predict if my fresh Isosceles Boost burns because of the 12V adaptor?
All my electrolytic capacitors are 50V rated, TC1044SCPA should work with 12V (1.5 V to - 12 V range) and TL071, as far as I understand, could manage up to 15V.
But I know next to nothing about electronics, so can not be sure.
Moreover, TC1044SCPA is extremely rare in my area, so it would be a shame to destroy one with my own hands.
Any help would be appreciated!
Have a nice day!

The absolute maximum supply voltage for the TC1044SCPA is 12V.

The charge pump circuit in the Isosceles is tripling the input voltage, so the TL071 will be running at near 36V. (which is also the absolute maximum for that IC).

Running continuously that closely to the maximum is probably not the best idea, any variation in your power supply output could lead to failure.

personally I wouldn’t as my experience with charge pumps is they are not at all tolerant of over voltage.

If that’s the only power supply you have to use, you could try running a string of a few diodes in series with the +12v to drop the voltage closer to 9.
