I am trying to desing a power supply, including a 12v flyback regulator
(it's for my incar mp3 player).
The regulator I have is a national LM2587, there are designs in the app
notes but all include a transformer. As I think I'll need more than one
regulator (for more current) I'd prefer not to. Is it possible to built
one with an inductor?

I don't know about the LM2587 and would need more details of what you
are trying to do. If you are connecting to mains voltage then you
need a transformer for safety/isolation. If you are converting from a
car battery or something like that then you can just use an inductor -
a transofrmer is not necessary. I do not know if the LM2587 is
suitable for that configuration as I have never used it, but certainly
other switching regulator chips are.
