Hi, I was looking for a Audio amplifier that can produce 3-10 [W] output.
also I need that the amplifier will have 12V input (This is my power supply and i dont wish to put a downconvertor).
I was wondering about MP7741.
I was looking at the datasheet and he seems perfect for me with 1 drawback that i wish to check.
In this scheme :
I wish to keep my PCB as minimal as possible, and since i only use 3[W] output, i was thinking, maybe i can change the electrolytic capactior to a ceramic one ?
if i can, what value of capacitor can i put instead of 1000uF? (digikey ceramic capacitor are maximum 600uF).
same questions about the inducter. I would like to change the Lf. Again, to minimize the pcb size. also, since I am only using 3W output, i dont think i need that kind of inductors and capacitors.
I would like to hear your tought about what i said, and if you have any idea on what replacment i could put.
thank you very much,
Michael.
