    I noticed that Nokia chargers have no internal SMPS chip to control the duty cycle, and yet they regulate the voltage via flyback smps topology, and I would really like to understand how that work.

    Anyone has a circuit diagram of some charger (and maybe some comment on it) that works like that? I wasn't able to find any on google.

    Sorry for bad english :)
