However due to unavailability of a heavy power supply and a good mixer, I have tested it on Soundblaster soundcard with the following data:

Voltage 32.5 Volts
Spk: 4 ohms 12" Subs.
Output : ~150W in each channel
Configuration of chip: stereo BTL mode
Board size: 80X60 mm

It is built with few changes in original Texas Instrument application note.

Please note that however TI claims the IC to be operated safely under 50 Volts, but never use more than 35 V with a 50 Hz transformer OR 43 Volts with a SMPS. Else you will burn the chip.

Please Email me if intrested in schematic & PCB layout at akjain2007@dataone.in

Wow!!! I can't believe that you made a TAS5630 board with single sided PCB!
Please continue your good work :-)

....in hope to see your future designs ...

Further, if you dont have enough technical knowledge of class D's, dont even think of making this amp because it requires much skill and knowledge to make it working (rather, sound it) otherwise you will only mess up with a lot of oscillations and burnt chips .

If anything is wrong in design, the chip simply keeps its circuitry dead and you will be unable to hear any thing.

I can also make PCB for you if you like the design.
