12v to 48v converter

Hi.

I need to find a schematic 12V to 48V 4 Ampere DC to DC Converter

Someone told me that i can do that with a UC3843!

The think is that i can't find a schematic! (Or don't know how... Because i am new to electronics)

Can anyone help me?

12v dc to dc inverter schematics

Yes, you can do it with a UC3843 or other PWM chips (such as TL494, for instance, although I prefer the current-mode UC3843).

Do you need isolation between the input and output? If you do, you will need a transformer and build a forward converter (you can get away with a flyback at this power level, too).
If no isolation is required, then a simple boost will do the trick. Let me know, I can help with schematics/ calculations.

VVV

First of all.. I would like to thank you all for your replies..!!!

You really helped me!

I think i will fix this circuit:

Please if you can see the picture tell me your opinion about it!

Thank you all very much!
 
Hi, you can use TL494 or uc3842,but i will search for the diagram and post it to you cos i build something like this using uc3842 and it works fine.
