The one on the secondary dnq1002d contains an error amplifier, opto driver and a bunch of comparators with a reference for fault detection. If the controller bd.

I see two TO rectifiers and that kludge Those little ferrite rod inductors are just for high frequency spike suppression. Looks like a bigger version of the w ones Astec built for Gateway midtowers late socket 7 and slot 1. I want to convert an atx power supply so dnx1002d it has a single output, about 6v to 18v and be controlled from a dc voltage power aupply for a ventilation fan.

Theres another device in dna0102d on the high voltage side I’ll look into what that chip is next. These two ICs are Delta proprietary parts.

Just saying hello Started by MichaelaJoy Yesterday at 6: Just with that Delta from a quick look today I am suspecting it may be a Mains side problem. PV charger battery circuit 4. Click here to register now.


Dec 248: What’re the maximum output ratings on that one? AF modulator in Transmitter what is the A? Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

WTH is that leaded dual-diode-kludge?! Articles Top Articles Search resources.

Yeah nice of them to put a line filter IEC connector for mains in. How can the power consumption for computing be reduced for energy harvesting? Pc power supply dna ic. Not sure whether the regulation is on the 5v line dataaheet the 12v line, I dont think they are seperate on this unit, maybe the 5v rail has a switching reg from the 12v rail. Digital multimeter appears to have measured voltages lower than expected.

Synthesized tuning, Part 2: How do you get an MCU design to market quickly? The thing I dont get right now is that the chip is on the low voltage side on the ferrite tranny. 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.

How reliable is it? Equating complex number interms of the other 6. Dec 242: According to the following link: Measuring air gap of a magnetic core for home-wound inductors and flyback dstasheet 7.

Page 9 of I would have that that even if shutdown protection circuits were firing to protect it, it should give some glimmer of life Anyway got a cheapie coming to replace it, so it will be a project just to know why it died. Its an old HP box I was going to use to play with linux. Ask them to e-mail you a pin-out diagram and a block diagram of the two ICs I mean when starting 12v output falls bellow Started by fastline Yesterday at 8: Potentiometer Questions Started by norbss Yesterday at That box now has the Gigabyte MB in it that I recapped.


But according to the following link: Heat sinks, Part 2: Here was my PM on this topic to Starfury: For a better experience, please enable JavaScript in your browser before proceeding.

I’m thinking that theres a feedback resistor divider and a reference voltage that I can tap into to adjust the output. Distorted Sine output from Transformer 8.

I’m thinking maybe this chip is the part of the circuit that converts 12v from the main output down to 5v. Hierarchical block is unconnected 3.

Input port and input output port declaration in top module 2. Forums New posts Search forums. Really must pull the Enermax and check it PNP transistor not working 2.
