Modify PAM8403 and TPA3116D2 to high watt

[pattarakamon]

I have implemented PAM8403 and TPA3116D2. Let's use the PWM signal to increase the high volts in the circuit I designed. It works well. I recommend it to work in the line, the short range speakers are safe and sound good. But if using a long cable, it should use a filter core.

Hi it looks fascinating but isn't it cheaper, easier and better sounding to pick a class D chip that simply has higher output power?

This is the PCB

This is the PCB that I designed to work with these two numbers.

This method uses two coils wind the wire in the same direction wound on the single core. which will give OUTPUT Still a full bridge, this is class D full bridge 2 times in one PCB.
use single volt.

Test +filter coil

TPA3116D2 to high watt +filter coil test.
No feedback, offset 73mV

how will you control 12V supplied CM4049 with a 5V supplied PAM? Looiks like the other nonsense you posted here under different names.

TPA3116D2 to high watt

The circuit in the PCB, I can replace the 7812 and 7805 in the PCB, I tested them all. I also saw a filtered wave. It was beautiful and it worked great.

Behind the filter core is a SPWM wave that changes according to the audio signal. It causes the carrier to be completely wiped out. And this TPA will resist clipping in the volt peak.

Very cool idea 🙂
I'll try it these days with TDA8932 class D amp.

 

[pattarakamon]

There are still a number of numbers that can increase the wattage to that high. and there are few that can solve the frequency

 

[pattarakamon]

L value, step down circuit=1.5mF .
not 150uF.

You you used inverter inbetween . Should nt pam3w and ir2110 be 5 v compatible already

Hai can you show me what's the output of pam8603 -out with respect to ground . And +out with respect to ground on 2 channels . Are They multilevel pwm .
