why you need it? for an op-amp or else. Some dc to dc converter will do the job but they're not cheap. you can build something with one 555 ... that's working.

OR with a simple circuit modification, if your PIC have a extra PWM output you can use it as pulse generator instead of the 555

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
