Hello Silvio. I was wondering if you can send me the pdf of the 700w smps with ir2153 project.
Hello Sir,

I'm working on Detex HD2500 PCB and I noticed that negative side step is not working like positive side step. Did you find any error on this PCB/schematic. In the same time I found that there are a missing additional transistor than in the yamaha schematic. And also I'm confused in the same time because in another schematic from powertech HD3600, which is almost the same schematics with Detex hd2500, negative side step is working properly. Where is the problem?

Please help.

Many thanks,

Mihai.
Hello Rinchz, I am sorry to hear that you had the earthquakes and also about the house. Its a bit quiet around here at the moment. You still can go to the older forums and read what others wrote over time. You still can gain experience in smps. Blog posts are also good and there are a few that I wrote myself. I make a lot of reserch when I do something and I learn a lot. I also try to pass what I learn to others so that everyone can get some knowledge.

I know that getting your house fixed again will take some time. I wish you the best of health and hope that you will settle again to normal life soon.

Regards Silvio.

thanks,
rinchz

Hi Delta67 If you want some information for converting an ATX supply I found a website that explains this in detail. The site is in Italian but you can use google translate to get it to English or another language of your choice. I myself found it very helpful and it can guide you very well.
