Swich Mode Power Supply 220Vac to 9-12Vdc 1A

Hi, I would like to build a switch mode power supply like phone chargers. Any voltage from 9 to 12 will do but must be at least have 1A. I've seen a schematic but the voltage doesn't meet my requirements and also there are no values or names for some of the components. The frequency for AC line is 60Hz. I attached the schematic below.

Any help would be much appreciated.

Cheers,

lloyd

Given the prolific amounts of such devices which can be had almost for the asking....everyone has assorted chargers from older phones, this must be a learning/teaching project of some sort. Old PC atx supplies deliver the 12VDC at many amps...

Hi thanks for the reading material Mosaic but I just can't build a project like this from scratch. It looks like it would take me more than two weeks to understand this thing. I hope you could recommend me a material a lot simpler than that one you've posted.

So then what is it you want to do ?

Switching power supplies are not simple, It would take a professional longer than 2 weeks to design one.

Funny, I did just that for many years..... but after reading some of the posts I keep seeing on these forums, I thought I must have been doing it the hard way since most people think it's a five minute job.

It's not.
