I was just checking a data sheet for the MIC1555 (an IC similar to the NE555 timer), and came across the following circuit:
I confess I find following such switching circuits a bit mind mending, but as far as I can see, surely this is at best about a voltage doubler:
As the output on pin 5 only switches between 0 and 5V (and not -5V like an AC voltage doubler), the maximum voltage that C2 can charge to is then only about 5V (minus a diode drop). C2 is then able to charge C3.. so the result should the C4 sees about 10V minus 2 diode drops. Or am I missing something?!
