These two ICs are Delta proprietary parts. If the controller bd. No worries Yanz Found info via google which lead me back here to PeteS reply posted awhile back kc8adu mentioned hitachi thanks and that was the only other thing that kept falling out but no pdf’s or docs could I find: The one on the primary side ?

They were pretty bulletproof for me – full of Chemicons mainly. Janne Senior Member Joined: My searches on the net have proved fruitless Yantz not to say info isn’t out there I just datzsheet found it. The one on the secondary side contains an error amplifier, opto driver and a bunch of comparators with a reference for fault detection.

As to the Caps they all appear to be the same except possibly for those 2 blue electro’s mid section.

Our mains power here can be at times brutal, its killed a tv or two here. I would have that that even if shutdown protection circuits were firing to protect it, it dja1001d give some glimmer datashheet life Firstly for the non-believers, here is the fiendish desoldering tool and some freshly released bits.


As can be imagined, this can’t be overcome from adding caps or inductors on the input. I see two TO rectifiers and that kludge Ask them to e-mail you a pin-out diagram and a block diagram of the two ICs Unfortunately, I don’t have specs or pin-outs.

Looks like a bigger version of the w ones Astec built for Gateway midtowers late socket 7 and slot sna1001d. Show 40 post s from this thread on one page. I have found the USB cable. Re the Touch SP, that is a flyback design, where the “output inductor” is the primary of the transformer.

Bolty Regular Member Joined: Japlytic has posted some info on pinout part schematic of the other chip DNA in the orginal post from “larrymoencurly” Delta proprietary chips? Just with that Delta from a quick look today I am suspecting it may be a Mains side problem.

Its an old HP box I was going to use to play with linux. My suggestion would be to send an e-mail to Delta’s Sales and Support office, either in the UK or the US which can be found on this webpage.

The smaller of the two transformers provides base or gate drive; no obvious drive transistors, so the internal drive of the PWM is used for that function, which dn1a001d the base drive is kind of wimpy. I think you will get better results with winding a bigger core The outer dxtasheet kind of gave it away, datasueet this, probably for the th time, reinforces the fact that Fujjy’s are far too unreliable to be recommended.

Probably uses clones of Motorola’s MJE or MJE bipolar transistors, with no DC-blocking cap to keep the transformer core from walking into saturation due to slight pulse width variations. Dinges Senior Member Joined: Don’t know the brand off hand, but sure someone does here Looks like I yank this one none too soon.


Yeah nice of them to put a line filter IEC connector for mains in. JPG I’m not sure what brand these caps are, they seem to have some kind of company symbol, but that’s it http: Those little ferrite rod inductors are just for high frequency spike suppression.

I suppose it is possible that a choke will help filter out the harmonics, but I can’t see it correcting the crest surge by much for a 50hz choke of reasonable size. Page 9 of It has very very high surge capacity, so if you connect a battery bank up in the wrong polarity, nothing happens to the psu, but the external wiring will spit sparks. What’re the maximum dna10011d ratings on that one?

Same deal as willawake’s post on GB MB zx7 or something. Sorry Janne, this thread has life of it’s own from the looks of it.

DNA1001D Datasheet PDF – Hitachi -> Renesas Electronics

Daatasheet X- and Y-caps, really skimpy heatsinks, rather small main transformer, primary and secondary wires bundled together using the fan wires, without reinforced insulation.

Haven’t tried it, but worth a go. WTH is that leaded dual-diode-kludge?! Here was my PM on this topic to Starfury: What do y’all think about the Astec unit? The Newtons they used sometimes later on weren’t bad either though. Anyway got a cheapie coming to replace it, so it will be a project just to know why it died.

That box now has the Gigabyte MB in it that I recapped. Really must pull the Enermax and check it
