Hi all...
I am trying to make a small step down converter (220v AC to 5V DC) for i need a transformer.
I got some transformer from my store room which were mounted and soldered on some of the scrap PCB boards, but i am confused what are this called and can i use this type of transformer with 2 capacitors to convert 220v AC to 5v DC.(image attached).
and also how can i calculate the rating of the transformer as it is nothing written on it. how can i know where is the input and output pin. as some has 6 pin and some has 8 pin
