I was trying to find the PWM Chip on any of them so I could attempt to disable it like this guy has done: Any ideas on where it is or what I should be looking for? Just saying hello Started by MichaelaJoy Yesterday at 1001sl Then get out yer ohmmeter, put it datsaheet gabeepen tooter, and start buzzing. Articles Top Articles Search resources.

There is some feedback across the isolation through the 3 white optocouplers, so it may be that i am wrong, but i can’t tell you for sure. By continuing to use this site, you are consenting to our use of cookies.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. However I am struggling to identify where it is on the pcb. I was expecting a standard ic in the supply but its a dna and I’m having trouble finding a datasheet for it, has anyone had experience of one of these ic’s? Check whether there’s a TL nearby.

Thread starter dr pepper Start date Aug 24, Media New media New comments Search media. He explains the function of these chips, and provides some schematics. Without knowing for sure i can’t find any hints when googlingit would be my initial guess that the DL is a power-factor correction IC, while the DS is the PWM system. The thing I dont get right now is that the chip is on the low voltage side on the ferrite tranny.

Depending on topology, it may be different. You should only need an amp or two extra, and those IC’s will output quite a bit more than rated in short bursts.

Want to add to the discussion? Not sure whether the regulation is on the 5v line or the 12v line, I dont think they are seperate on dqtasheet unit, maybe the 5v rail has a switching reg from the 12v rail.

If the problem is truly an engineering problem, we’ll allow it, but fixing your laptop or a cracked LCD screen doesn’t qualify. Keep brand wars to a minimum.

Those white rectangles, southeast of the “1D4” chip, might be opto isolators. My device is a smd and its 16pin, however I think its just a diffo package of the same chip. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Log in or sign up in seconds.
