Hello,
I am struggling to find a suitable transformer for the LM2585. My needs are as follows:
1- input voltage 24V;
2 -output voltage 60V;
3- configuration: flyback;
4- power: 20W output
Currently I am using the WE 750313976, which works well but cannot handle more than 5W, and I don't seem to be able to find a commercial product capable of sustaining the 20W I need. So my questions are:
1- are you aware of any commercial transformers suitable for my needs?
2- if not, what parameters do you suggest for a custom transformer? I have experimented a bit building a few test transformers and I have determined that :
- the inductance of the primary winding to be between 50 and 100 uH; do you agree?
- the winding ratio between primary and secondary to be 1:4;
- I have tried a couple of different cores, but I have ben unable to determine exactly their composition; what core do you suggest and what size?
- what size should primary and secondary winding wires should be?
Thanks,
Paolo.
