Hi Jozef, Thank you very much for the article.
Virgin Galactic — Commercial Space Flight. I need it to run 18v only. As written in the article above, this tutorial covers only halfbridge TLdriven supplies. Forums New posts Search forums. I uploaded a video on youtube of it: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at This was the third ATX internal variable voltage supply. TL pin1 the voltage feedback.
I sounds like it might be easier to just build a supply to do the job you need. Excuse me, but I cannot understand where exactly to connect potentiometer which pin of TL Hi and thanks for your comment — yap, noticed the inrush of views. They had use only a 50k pot mount on pararel on 12v rezistor feedback.

I have Corsair TX power supply which I want to convert. But it gets better even, when you connect 3. Thank you for the reply Jozef, if it works or vbl339 I will post my results. Nice text, thanks for sharing this with us. For every different kind of supply the approach is the same, however parts involved might differ a bit.

Use a desoldering pump or nipper pliers, the choice is yours. Nope, the V is a separate tap and usually has a maximum current rating of mA.
And a lot of diodes, resistors, transistors, caps and a coil in the low voltage part with 10 leads. Only interested in say 7. ATX supplies do have a separate ferrite transformer powering the regulator microchip, in db3l39 case. You are going lose the original short circuit protection this way, too.
However one thing I could not solve. Started by fastline Yesterday at 8: The main chip is a DBL, so all went fine. Hi Jozef, Nice mod you did! Can I do that?
If you do not, it is not advisable to proceed. After that, you can post your question and our members will help you out. If rated 12V 8 amps then it can only supply 6 amps at 16 volts. Your hack is today on Hack a Day! Hello I need help regarding your scheme. You must xatasheet in or register to reply here. Whoa, now those seem to be real exotic chips.
Hi, nice job on hacking this ATX power supply! In addition, ATX supplies are not something scarce, so get a few to experiment. What kind of modification should I do?

The controller ic is a g. Meh, trying my best to explain, hope you understand! I think the overload protector shuts datasheeh down.
Click here to register now. Thanks a lot for the hack! I relocated the grounding resistor to ground the feedback circuits. Could you tell me which ones and with what parameters? Basically the maximum output voltage you can achieve is going to be determined by the winding on the transformer that supplies the 12v output Inverting input of 4 th comparator.
I bet theres a Zener in reverse polarity parallel to one of the lines 3.
