It's pretty interesting! It looks like it has a triangle core, with a 3080 OTA dumping current into a cap - but it gets kind of weird from there. There's a second OTA and a weird NPN/PNP (Q5/Q6) pair that I, uhm, think is acting as a comparator, but I'm not sure. 

Has anyone dug into this? Does it have pros and cons?
