Hello,
I am doing the following DCM Buckboost LED driver….
Schematic:
http://i50.tinypic.com/5yi929.jpg
Vin = 9-100VDC
Vout = 40 to 72VDC
I out = 90mA
This converter was extremely difficult to compensate.
Would it have been easier if I had used the TL431 instaed of the LT1006 opamp?
LT1006 Datasheet:
http://cds.linear.com/docs/Datasheet/1006fa.pdf
TL431 datasheet:

I hear that the TL431 has a poor quality internal opamp, and I felt that this would make feedback compensation more difficult?
