- I only address this point:
- > Are there some other way how to do this which I have not covered?
- Yes. Instead of using boost and buck converters, you can use integrated charge pumps. They don't use inductors but only capacitors.
The only one i could find (in my very short search) that has 2 symmetric outputs that can deliver 12V was the LT1026IS8 IC. But you have to check if it really works the way you want it.A other option could be using a RS232 driver. Sometimes they have charge pumps to generate outputs of +12V and -12V. But you have to check that yourself.If you are ok with using 2 ICs instead of only a single one, there are many charge pump ICs available. Go to your favourite shop and search for »charge pump IC«.

- The only one i could find (in my very short search) that has 2 symmetric outputs that can deliver 12V was the LT1026IS8 IC. But it only double the voltage. Maybe you could cascade 2 ICs to generate more. But you have to check if it really works the way you want it.
- Honestly, i don't see the advantage over boost converters. What stops you from using a boost converter? When you need more than double your voltage, a boost converter maybe the better option over charge pumps.

The other option is of course, building a discrete charge pump yourself, with discrete semiconductors, but that is more likely more bulky than any IC solution.
