hi guys ,if anyone is intereted in car amplifier,pls feel free to contact me for large quantities,my skype:henjoyan my email:flyele@hotmail.com
Hello,
Guys I am going to etch a smps board , It is double sided.
I a double sided board w, i dont know how and where the top layer connects with the bottom layer. Please guide.

Double sided PCB
Hi there,
Double sided PCB making requires precision. You must have a PCB properly laid out based on its schematics. Laying out the tracks would be relatively easy as long as you have reliable software to use. Parts placements also plays a critical in making the circuit reliable. In terms of current handling for the tracks made on the board.
If you have the PCB layout sample, please post it.

why don't you use toroid? would be much more easy to do it
And I have have my doubts that you will need that much power...
you are going to use this as part of car amp? if yes, what kind and what will be the load

It will be 3 channel amp
2 channels stereo-120watt rms at 4 ohms, needs 6 amps on regular psu
3rd channel mono- 250watts rms at 4 ohms, needs 5 amps on regular psu

and you would be wrong here, since even sine does not consume that much power, let alone music... with this you would only need peak power of say 500w, not constant... which means you can make a lot smaller supply... and even more, if you have more output capacitance, you have there stored a lot od energy, that does not need to be transfered from primary side, since it is already stored in output capacitors
then again
make 2 supplys, one for low powew amps, and one for higher
coz you don't need +/-55v on class AB amp to waste most in heat for 120w of output

I am making Ax-14 By apex for stereo.
For Mono Amp i haven't yet finalized, I am having hv350 by apex in mind. Do you have any good Pcb layout of sub amp with output of 250 watts @4ohms.
Also layout of Smps for these amps.
I am trying to make all these made on a single pcb.
Hoping for the best, lets see.

no, I have a bit stronger amps just for front stage, subs get a bit more power than that 🙂

well... yes, if you don't have too big alt, that would charge in 15v range...
its also good to first know that your trafo is made good, while spikes from swithching are not a problem for fet, you should still make sure before you install it for ever
also, unregulated might be better, since its always full duty, but can't say for sure
I would say you are cutting it close, more then needed, coz unless you already have the fets, I would look for atleast 40v ones

Well, I have plenty of high voltage FETs. I was just wondering if a mini 50-100W supply could be made using the small 30V SMD FETs TI offers.
if for car use, get 40v, really puts you more in the safe zone, then with 30v
if it was of a 12v source, then 30v would be more then enough... your call, for test you can always use 30v

hey, i have no knowledge about electronics but i'm curious if rod elliotts smsp will suit with Hiraga's Lemonstre amp. thanks in advance
Which components will a have to change, to reach more AMPs? I would use IRFZ44N mosfets, core for transformer (similar sizes to ETD39) from ATX psu, bigger bridge and bigger capacitors. On the high AMP PCB traces I would sold extra copper wire. Anything else?

components are not really a problem to some point, since you are going with relatively small core, core is the first to be maxed out (at some freq.)
single 44n per side of the push pull would be good for at least 400w.
also depends on what you want to make it for.

If anyone is willing to build a SMPS to power 2 F5 amplifier boards for me please PM me. This is a bit above my skill level and I would really like to try these amps in car on my horns.
