I have been on a binge of trying to fix these things.
the CX22011 has become unobtanium at this point, and I ventured down the path of re-engineering that power supply before ADHD brain took over and i sidelined the project. Trying to make something that still operates within the parameters of the original so you can still get the synchronized ramp for the parabola is a bit... difficult. The reference point isnt common anymore for newer PWM ICs. I need to figure out how to adapt without changing the loop gain, aka stability of the overall circuit design.
I wished the actual SV1 and SV2 schematics were out there.
