The best part is that if i turn off the first PSU i still get the voltage from the 2nd one and vice versa, so dbk339 get either a V regulated PS or a V regulated PS. Sep 26, 5. Output of 4 th comparator. Then, make a circuit like this — the values specified are good for a start; you might have to tune them a bit for your setup.

I had to, because otherwise the two psu would have had the same ground. Ask a Question Want to reply to this thread or ask your own question?

This allowed me to adjust the 12V db339 from 14V to 6. Double-check the circuit you have made in step 2 and whether you have wired everything properly first. Hi and thanks for your comment — yap, noticed the inrush of views. First of all, thanks for posting this great idea. Accordingly, the 12 volt supply might only be good for 16 volts tops but remember corresponginly less current as well.

Choosing Battery for Robots. Thanks for the great tutorial, i have succeeded to convert an atx supply by following your tutorial. I think it can be useful. Modding a Vivitar flash unit.

However one thing I could not solve. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at In common applications, one of the pins is provided with a reference voltage and the other one receives analog input from a sensor or any external device. Output of 2 nd comparator. Basically the maximum output voltage you can achieve is going to be determined by the winding on the transformer that supplies the 12v output Basically, you should see at least 3 ferrite transformers on the circuit board and a heatsinked linear stabilizer 78xx powering the chip.


Mosfet New Member Aug 10, Extra in-line fuse should do the job. Forums New posts Search forums. Articles Top Articles Search resources. The old power supply is doing nothing useful so I might as well give it a try.

As for your particular PSU, I have no idea what reference voltage is used in it. So what I did: Sorry for my english. Btw, there was no linear regulator at all. Sep 25, 2.

If i short pin 4 to ground over 4k6 resistor do I still have over current protection or do i lose it?
