I am designing a primitive flyback converter with no feedback. I was considering to accomplish the switching by means of a PIC and a MOSFET.
I then stumbled along this chip: MC34063A , which (correct me if I'm mistaken) does the same thing. It is programmed with this tool.
Is it correct to say that for a given frequency and duty cycle, it outputs the given voltage and current, then opens the "switch"?
If so it seems to meet the bill, the only problem is that I need a low frequency, circa 100hz. According to the spec its min. frequency is 24khz.
I then stumbled along this "variant", which claims to have a min. of 100hz: KA34063A.
Does this solve my problem? If not, is there a better way to do this (looking for low cost and simplicity)
Any response is appreciated
