Re: Flyback with LAN transformers

Joerg a écrit :
Ok, most of us have used LAN tranformers for power transfers. However, their datasheets are skimpy at best and usually contain no information about the core. Of course it won't contain any regular air gap and you cannot easily install one later because it's all potted up.

So, did anyone use these for a flyback design yet? Low power, something well under 100mW.


Which voltage from which voltage?
Do you really need flyback? I once did a funny self-oscillating one for that kind of power, from 50V supply. Worked pretty well with about 60%, maybe 70, efficiency IIRC.
I can dig up the drawing.

Anyway how about measuring your xformers? That's so easy...
