I think I’ll pull another psu out of my stack of scrap bits and look at that one. The PSU is shutting down on me with overcurrent spikes in my application. Click here daatsheet register now.

If you have specific, targetted questions regarding homework, we will 1001rl you out only if you have provided some beginning work. 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.

Keep brand wars to a minimum. Potentiometer Questions Started by norbss Yesterday at Articles Top Articles Search resources. I remember your last thread. Different products have different specs – if you’re an engineer, keep discussions purely based on merit.

And what section of the circuit needs to know this? SMPS use a TL to detect the output voltage and report back via an optocoupler whether the output voltage is too low or too high. He explains the function of these chips, and provides some schematics. That’s what yer lookin’ for, right there. This chip is almost universally used in SMPS because a everybody else’s supply uses it; b it works so damn well; c it’s part of the example circuit on all SMPS power supply controller datasheets; d it’s so damn cheap.


Power, electronics, electromagnetics, semiconductors, software engineering, embedded systems – it’s all fair game!

Started by fastline Yesterday at 8: I was trying to find the PWM Chip on any of them so I could attempt to disable it like this guy has done: 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 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? Thread starter dr pepper Start date Aug 24, Check whether there’s a TL nearby. You might be able to hook up a scope to some of the pins on those chips and see which one changes when you load it up to the point where overcurrent daasheet in. You should only need an amp or two extra, and those IC’s will output quite a bit daasheet than rated in short bursts.

It was probably caught by reddit’s spam filters.

Trying to ID the PWM Chip on a Dell ATX Power Supply, help appreciated : ECE

I’m thinking that theres a feedback resistor divider and a reference voltage that I can tap into to adjust the output. The LM is an opamp, as you say. You must log in or register to reply here. Media New media New comments Search media.
