Hi Folks, One other questions, I've been trying to get a MAXIM 770 Step up Power Converter running from two "AA" Cells to +5V without much success. I've tried to follow the datasheet for the "bootstrap" mode device. I originally wanted to use the 756 device because it could be used to drive the reset line of the PIC (and use the PWRTE), but I haven't had any luck finding the devices. Does anybody know of any sources? Digi-Key doesn't stock them and I can't find any local (Toronto) Sources. Thanx, Myke Myke "We're Starfleet officers, weird is part of the job." Capt.
