Wow - you guys really know your stuff! This is great info. I really appreciate the explanations. That diagram was exactly what I was looking for so thank you very much. I have been reading those FAQ's and will continue to do so before I post anymore questions. Also - Thanks for the explanation on PWM. That makes complete sense how you explained it.

Dave - Those documents are a little over my head. (Actually WAY) over my head lol. I had a look through them tho and it made me want to dig out my circuit analysys books! haha

Well - gotta run! Thanks for the info yall!
