IRS2092 How to drive more then one pair of output transistors?

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.

Here is the PCB and layout but I can't find the schematic.

What do you think about this one?

These boards use TC4420 6A peak mosfet driver ICs

hi realforce
greetings how many watts per chaandrew lebonnnel
thanking you

[Cristi]

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

I have more info. Here is everything I could find nd IT WORKS. It is also commercial.

Can you show me one that uses more than one pair of output transistors?
