Swithing Power Supply !

[-_nando-_]

Hi everyone ! 😀

As everybody knows, the most difficult part in a Car AMP is the PWM Supply...

I found this :

http://www.datasheetcatalog.com/datasheets_pdf/L/M/4/9/LM494.shtml

This CI is for Swithing supplies, you can find this CI in computer supply, and car amplifier 😉

Well... There's the FETS too... IRFZ44 / 46, depending of the current...

Ok, but I don't have any ideia how to build this !

Anyone here have a schematic of a Swithing supply ?

I think if we want to build our car amplifier, we HAVE TO build a good supply, that we can modify the current and voltage depending of the project, then will be very easier to all of us to build car amplifiers... 🙂

So, let's work together? 😎



Thanks !!! 😀
