A note to add: So shemathic should be very close to W datashdet. Could you please check the datasheet of this IC and telling me which pin should Dl339 desolder to proceed?

You are going lose the original short circuit protection this way, too. Hey Pieter and congratulations you got it working. Disconnecting or grounding those sensing pins — V33, V5 or V12 — might prevent the supply from starting. As for your particular PSU, I have no idea what reference voltage is used in it.

Daewoo Semiconductor datasheet, Daewoo Semiconductor pdf ::

Now, do you think I can try your mod using pin 14 of IC? A comparator is a simple circuit that moves signals between the analog and digital worlds.

On a sidenote, have you submitted your project to hackaday and instructables? Basically, you should see at least 3 ferrite transformers on the datsaheet board and a heatsinked linear stabilizer 78xx powering the chip. I would like it could start from zero volts. You must log in or sign up to reply here. Using a 5k trim pot to set max high volt 14V on the 12v line and a 10k pot in series, to adjust the voltage.

If you do not, it is not advisable to proceed. This is a great idea!

Sep 25, 3. So this may fires transformer? Nope, the V is a separate tap and usually has a maximum current rating of mA. Forums New posts Search forums. This is a real ATX to regulated supply conversion, which might come in handy for you. First I get some strange noise inside supply then when I connect bulb 5W supply shut down.

Non-inverting input of 3 rd comparator. LM is a comparator IC with four inbuilt comparators. I have a Thermaltake, Toughpower watt xt. Thanks a lot for the hack! So, here is how to do it. Any idea what this could be? Its designed to provide PSU protection, power good output and protection detection. The large transformer has a center tapped primary winding. Then you can adjust the output down to zero. Here is one schematic with SG that might help in further experiments with this sort of supplies.

Where did you get an extra 12v line in your prototype?

First of all, thanks for posting this great idea. Whoa, now those seem to be real dbl393 chips. In addition, ATX supplies are not something scarce, so get a few to experiment.

Well done, this is an excellent hack. Media New media New comments Search media. After you are finished with step 2, this is important: Chippie Member Mar 9, Came out of Cooler Master tower.

I had to, because otherwise the two psu would have had the same ground. Use this as a last resort and install some kind of a circuit breaker or fuse in series with the output. Check your wiring, confirm output voltages as described in the article with a voltmeter. Hello I done all datashdet you datashset write.

If it tripped the breaker and burst in flames, then I hope you have read the Disclaimer before attempting this conversion, as you were instructed to do so at the main page.

The problem is, the schematic is quite complicated. Interface GPS with Arduino. Beware however NOT to exceed the voltage rating of the filter capacitors as these will readily explode if used outside their specs.

But it gets better even, when you connect 3. However one thing I could not solve.

As written in the article above, this tutorial covers only halfbridge TLdriven supplies.
