what transformer options are available for 220V step down?

I have been trying to find a viable transformer that is available for the assembling option. I cannot for the life of me find any transformer that can step down 220V AC or DC to 12 to 6V. Can anyone help me?

I don't know if the Filter options are any better on a pc than on a smartphone but it is impossible to select a transformer from LCSC Power Transformers pages without carefully studying the images to reject any that are obviously ferrite cored and then downloading the datasheet for each one that looks like it might be a mains transformer. Even then the most likely looking ones from VACS are so poorly documented that they do not state input voltage ranges. There is nothing there that has anything like a suitable turns ratio. However, you need to clarify the statement: "...step down 220V AC or DC to 12 to 6..." Do you mean 220V to 12V AND 6V or 220V to 12V OR 6V? I suggest you look elsewhere and be prepared to assemble the transformer onto the PCB yourself: [https://www\.bitsbox\.co\.uk/index\.php?main\_page=advanced\_search\_result&search\_in\_description=1&keyword=Transformer](https://www.bitsbox.co.uk/index.php?main_page=advanced_search_result&search_in_description=1&keyword=Transformer)<br> <br> Or RS Online, Farnell, Newark, Mouser, Digikey, etc.

@nesnah.daniel, You aldo need to specify secondary current(s) or VA ratings.

@nesnah.daniel, Had a deeper search: I could not find any mains transformers on the LCSC or JLCPCB sites.
