I was trying to find the PWM Chip on any of them so I could attempt to disable it like this guy has done: Articles Top Articles Search resources.

Those chips are proprietary chips made by Delta and there is no datasheet for them. Not sure whether the regulation is on the 5v line or the 12v line, I dont think they are seperate on this unit, maybe the 5v rail has a switching reg from the 12v rail.

Check whether there’s a TL nearby. Then get out yer ohmmeter, put it on gabeepen tooter, and start buzzing. Theres another device in there on the high voltage side I’ll look into what that chip is next. Thread starter dr pepper Start date Aug 24, 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.

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.

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?

Any ideas on where it is or what I should be looking for?

The PSU is shutting down on me with overcurrent spikes in my application. If you do a google 1001el search on DNA and DNA you will find some schematics, any you may be able to piece together some info on those.

It was probably caught by reddit’s spam filters. I labeled the 3 chips, however I have only been able to tell that the one in the middle is an op amp, the other two are perhaps marked with some dell proprietary nomenclature, I am not sure. I want to convert an atx power supply so that it has a single output, about 6v to 18v and be controlled from a dc voltage power aupply for a ventilation fan.
