Nice work,

This is my test build with the G300 module:

I'm in the process of having a new backplate laser cut to allow two modules in one case:

Dear gooki,great works indeed!

we have developed new smps fitted for full power function board,we are not suggest using TAS5630 at full load conditions,but it like a big pool and save high energy inside,so we can get more powerful bass and bigger dynamic range.

Schematic so simple ,use two flyback SMPS to realize it,only FLB SMPS topic can be in series and in parallel.auto current sharing when in parallel.

50V/10A continous current output(test at 220VAC),50V/12A at burst mode.if you use it at 110V delivered power will less.

authlxl, new SMPS looks good, do you have matching TAS5630 amplifier board to go with it?

Also what is under the heatshrink on the speaker output wires?

Ok!the common mode filter on the speaker output wires,decrease the output EMI,

the matching TAS5630 amplifier have finished,I have upload picture on diyaudio,here I reload !

Default Tas5613 have on the market,use easily!

If the tas5615 hard to use,the tas5613 cheaper and use easily,beacause it can drive 8ohm or 4ohm loader,sound quality excellent,not hard like TAS5630,and hardly burnt when shorted.

we use it on our TAS5630FFDV2 board,feature good.
datasheet :Digital Amplifier Solutions - Analog-Input Class-D Speaker Amplifiers - TAS5613 - TI.com
TI EVM :http://focus.ti.com/lit/ug/slou286/slou286.pdf

Works stable together with our atx SMPS 150 RMS power out,300W pp power out.

Soft start cap should larger than the datasheet value.

Sorry of my Chinese English!

TAS5613 use 36VDC power supply,works stable than higher voltage supply chip,when shorted protected immediately.

Our ATX 150 SMPS can deliver out 150W power continues,300W at burst mode.can not continues.so we call peak to peak power as pp power out.

Do you mean that TAS5630 sounds hard or that the chip is hard to use when designing the amp module?

We mean TAS5615 suit for 8ohm loader,not suit for 4ohm loader,sound quality excellent.TAS5630 and tas5613 not only can drive 8ohm loader but also 4ohm loader,use easily!!
