    Identify Component for Allied Telesis POE-Switch

    Hello,

    I need to identify this component from the power-supply-board for allied telesis AT-GS950/10PS POE+ Switch.

    The switch is working generally, but there is no POE function and I found this blown component.

    Appreachiate any help.

    Did you look for the missing plastic from the ic, it may be in the case and might have a number on it. On the part of the ic that is still there, (left side), is that something printed on it?

        I found an ic with a similar logo (likely China) but on your ic next to the hole it looks like part of a number 3 or could be a 7?

        I'm sure the next poster will have the answer

          I’d rather wonder if you take that IC off what the pin out could be a match something based on that?
          does it drive 2 MOSFETs? They are toasted too.

            Help making a switch work the opposite way with a relay
            by SluggerB
            I have a very small float switch, I'm using in a very small tank. It only fits in one way. Link https://www.amazon.com/uxcell-Switch.../dp/B07DZ1J2GB

            I want the switch to be open when the water is high, and closed when the water is low. Unfortunately it works the opposite. And since this switch is designed to be underwater, it's all sealed up, there is no taking it apart or hacking it up.

            It will be driving a water pump, basic idea, when the water is low, switch closes, which turns on water pump, when enough water is in the tank, float switch floats,...

            NEC TurboExpress On/Off Power Switch Replacement Help
            by grimacelord
            Hello,

            I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.

            I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.

            I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....

            Micro Momentary Push Switch?
            by Natob82
            Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...

            220VAC locales... ever used DC to feed switch mode power supples...and how many volts is generally okay?
            by eccerr0r
            For those in 220V locales, anyone power their SMPS with DC, and how high of a voltage is okay?
            What kind of PSU?
            I suspect that 240V * sqrt(2) = 340V DC is probably fine because that would be about how much the the primary rectifier ends up with peak voltage. Just wondering, other than input capacitor voltages, can one go up above this 340V without damage? Will that input capacitor be the upper bound?
            Wondering if exactly that, can I feed near 400VDC into bona fide specced at 220V SMPS without damage?

            Currently have a 120/220V switchable SMPS I want to see if I...
