500w Class D amplifier

[lcd950]

I would like to build a 500w amplifier without a transformer. Is it possible to build such an amplifier without a transformer?

I found below attached IC datasheet, could I use this IC for make a 500w amplifier without a transformer?

without a transformer. Is it possible to build such an amplifier without a transformer?

Without transformer, nope!

But with:

660W Switching Power Supply ?SMPS?for Power Amplifier ±40V ±50V 7A and ±20V 1 5A | eBay

And:

L25D Stero Power Amplifier Kit IRS2092 IRFB4020PBF 250W 2 8ohm | eBay

A transformer/SMPS adds safety to the circuit.

Then, can suggest me a 500w class D stereo amplifier, which can build easily.

Go with zeonrider's suggestion - buy the two items they linked, a suitable case, power/speaker/audio connectors and throw it all together.

I have L25D x 2 & driving 2 x 15" loudspikers.

Sound....😱......madness

What voltage are you feeding the L25D modules with? 🙄

+ / - 65V.

Do you have schematic diagram of this L25D?

Maybe the same.
