As I mentioned in another post re.inductors Im working on a switch mode battery charger bassed on the MAX713.
I am using the parts Maxim suggests on page 16 figure 19 of the MAX713 data sheet.
Some of the parts are made by several different manufacturers the 2N2907 PNP transistor for example. Im using the part made by ST.
Do the different manufacturers of the same part use the same pin out configuration? Is there an industry standard?
Another question. What are the criteria for deciding to use a NPN as opposed to PNP transistor in a given application?
