IRS2092 How to drive more then one pair of output transistors?
In the original datasheet there is only one pair of transistors. How can I wire 4 pairs of transistors like in this picture.

the layout looks great !!!!
but for a class AB amplifier only....
i wonder if we can see with a scope the signal on the Drain of the top MOS-FET's, close to the small 12V connector.
how many Watts they are able to deliver ???

Hmmmm I think this is class D amp. It uses IRS2092.
I would really like to hear if someone has made this.
The problem is that I can't find the schematic ANYWHERE. I only dig this PCB layout. So we must build it to test it 😀
I'll try and draw the schematic in eagle from this PCB.

it sure is, but what he is saying is, PCB is made for AB amps, if that 😀
BTW, it will be waste of money, even if it will work, there is a lot more to D amps then just throw some parts together

Use SMD (SOT-23) local buffer transistors (emitter followers) for each output MOSFET.
Although, this layout may work, parasitics make switching much slower resulting in much worse efficiency (and higher distortion) than in a proper SMD layout with 2+ layer PCB.
Parasitics will also limit the maximum rail voltage for safe operation.
3000W are possible with just four IRFB4227 when layout parasitics are low enough.

for diy I don't see how you would need more then 1 pair of fets for output, even with one it is ahrd enough
hi eva
greetings can this circuit be constructed as it is with 3 output pairs
what output power would we get
thanking you

In my opinion it should work really good. I am not sure if UCP700 works on the same principle or it is full bridge but the only thing I am afraid it is the PCB design. But it is not that bad.
hi realforce
greetings how can we know if pcb is designed properly for
d class after all most important criteria is ground plane how does your
prototype sound
thanking you
