    Looking to Substitute Fairchild KA3511 PWM Controller

    Hi,

    I am working on a PSU and suspect that the Fairchild KA3511 Controller is gone. I have hard time to find replacement and wonder if there is substitute from other brands that I can use.

    Appreciate if anyone can help out.

    Thanks.

      I've never seen them except in Fortron-Source-Sparkle-PowerQ-Powerman PSUs. Does Fairchild sell chips directly to the public? I believe that their parent, National Semi., does and even has a sample program, but you have to pay shipping & handling.

          ASUS ROG Strix- G513IH-HN008, G513-6050A3249301- MB-A04 (A4) damaged Embedded Controller
          by master3112
          I have an ASUS ROG Strix- G513IH-HN008, motherboard G513-6050A3249301- MB-A04 (A4)

          When I received the device, the device has no function. After an investigation, I found that the PWM CONTROLLER RT6575B (U6100) is getting warm and there is a short circuit at the 3V3 output. This normally supplies 3V3 for the embedded controller IT5571E-128 (U301). When measuring and analyzing with a thermal imaging camera, I found that some components are damaged: SLG4E42553VTR (U8500), IT5571E-128 (U301), LAN RTL8111H (U450), LOGIC 74LVC1G08GW (U1900), RT6575B (U6100) All these components are on...

          Help with freemotion incline trainer with controller comm error
          by ronnygracias
          The treadmill was working fine, one day the belt snapped and after checking the unit I also noticed that the display is now showing the Controller comm error. So I opened it up and the treadmill had two boards. One is a power supply board and the other is the motor controller. I noticed there was a mouse nest, so I took power supply board out, cleaned it up, replaced the big capacitor and that did nothing. Then I took apart the motor controller and cleaned that up, and when I plugged it in, it started right up. I thought I fixed it. But when the belt arrived, I installed it and tried to power...

          I bought a used replacement controller board that also had issues that I was able to fix and now the tankless water heater works correctly now

          However I would like to know if I could figure what happened to this controller board if possible

          Lift Master Garage Door wall switch display / motion sensor controller display disappeared no back light
          by sam_sam_sam
          This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

          I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

          I am comparing them to a brand new one that I installed

          The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

          I going to let it run for several days before I remount back on the wall next to the...

          Modifing a Battery Spot Welder because of Controller Issues
          by sam_sam_sam
          I keep having the same exact issue with these battery spot welder controller boards

          They either do one of two things

          One the controller does not send the signal for the transformer fire which is a very common problem with this controllers micro controller failure

          Or

          The controller has some malfunction which means that it does not cycle the pluses more than once or none at all and should do it any where from 1 pluse to 20 pluses because you can not change the setting does not respond to its input micro controller failure

          This...
