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

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 .
