    TL494 PWM Controller Module Booard to control a SMPS switching power supply are they available for this purpose

    I have seen some board on eBay and Aliexpress but I have not seen any for SMPS switching power board modules I would like to build one if I can not find one that is already made

    Dose anymore known if there is such a module and where would I find some

    While searching this topic on google I found this

    https://www.badcaps.net/forum/troubl...anything/page3

    I have read through this I have some switching power supplies that use the TL494 that if I can not find a readymade circuit board module then I going to breadboard one because I have several switching power supplies that have different voltage outputs i going to see what is different between each one plus look at application notes for this ic chip

    or dissection of a TL949 ic and its supporting components and make a board this way however this is my last choice

      Here is a good explanation of the use of a TL4949 based smps switching power supply

          I going to do some very in-depth research on this topic and see what I come up with

              Don't know if this helps, but here is TI's paper on the TL494, https://www.ti.com/lit/an/slva001e/slva001e.pdf .

                  Thank you for sharing this I had seen it earlier today while researching the topic

                      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                      by sam_sam_sam
                      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

                      Modification to a ZD-987 desoldering/soldering station using a external switching power supply
                      by sam_sam_sam
                      I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

                      I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

                      LG VCR-DVD RC689D SMPS Switching IC identification
                      by dkneyle
                      After sitting in Standby mode for years(?) the owner decided to power up and play a CD. At which point the magic smoke emerged and it died.

                      Upon opening I can immediately see the main charge capacitor has dropped its guts (literally). The switching IC is completely physically destroyed so I can't read any type number. I should be able to work my way through the other components; I can usually get a SMPS going. (I can see at least one bulging electro; they'll all get replaced.) But I'm hoping someone might be able to suggest the most likely six-legged IC that would be used?

                      Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
                      by sam_sam_sam
                      I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

                      This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

                      After all of...

                      Onkyo DX-V500 Laser Disc Player - weird SMPS fault
                      by dkneyle
                      This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.

                      Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS...
