The data sheets for these are available at: http://www.unitrode.com/sect-6/uc3906.pdf and http://www.unitrode.com/sect-6/uc3909.pdf They've got a few apnotes on these as well, unfortunately they're not on line. If you just want to scope Unitrode then check out: http://www.unitrode.com/ Scott PS Bryan, do you have my unitoad data book?
