Hey Ron I've got another question. Everything is working out and calculating fine now especially since I laid out a PCB instead of using bread boards. One thing thought I don't understand is that when I calculate the frequency with my timing cap ~200pF which gives me 8 or 9uS on time which is verified on my scope to be 8.4uS. This yields a period with a 20v input and 5v output of roughly 32Khz and that part matches up. I don't understand the extra pulses though in my on/off switching wave form. Below are the scope traces:
Scope traces are looking at pin 2.
Between the two cursors I get a frequency pretty much on the money, but why are some of the other pulses paired up so close together?
Thanks,
Robbie
