I am developing a 2000V flyback converter that operates from 2 'AA' batteries. It's driven by a PIC18F23K20 running a PID routine, and CCP2 to control the charge/discharge timing. It can run both constant voltage and constant current.
It is currently up and running. At constant voltage, I am getting +/- 0.5% regulation into a 15uA load from 2.0 to 3.0V supply.
Constant current regulation is much better (there are reasons for this!).
Not looking for any help. It is an interesting project, and I just wanted to share. Happy to answer any questions!
