220v flyback
I try to make a flyback power supply for my matrix display. I used PC power supply before but it's too big and complex. I want a small . I have a lot of old PC AT/ATX. Can I hack them? (At least, I can take some component).
I will draw some shematic to post soon.
But I confused about the equation to estimate Flyback Transformer.
It will two output:
- 5V, 500mA
- 3.3V,
May anyone give me an ideal to start?
Thank you for read!
