I'm looking to make a smps for a car amp

[radio]

I need a +/- 22Vdc to run 8 TDA2052. I was thinking about using a TL494.

Hi all!!
The question of this topic was: Look up a topic you have drawn all the way in quite another direction??
The right to tell you and I need this SMPS (project) for stereo amplifier with LM1875 [2x(22...25)V/2x5A].:UP:

Try this one.

Hello MicrosiM!
Since you're a great expert in SMPS so please give more details about the development of the ferrite transformer TR1 fed (see schematic)??!
What type and how winding enameled wire should have a primary section and with which and how many turns should have sekunar with which section?
Thank you for your eventual answer, believe me you will be thankful and other visitors of your forum that is the topic.
Thanks and cheers!
