How to make a stable car amplifier with TAS5630

[authlxl]

TAS5630 have largest power out within single chip,I think it should be develop and use in car audio amp.
4×225W/4Ω/1%THD@50V, double chip,safety ,output parameter is good,but how can we get regulated voltage @ large current out by easy way.

If the amp efficiency is 85%,the PSU should deliver out 1100W@50V at least.
the PSU should have 1300W convert ability, we have to make 12v/110A battery power to 50V/26A DC regulated voltage power.

I think it should have so much ways to resolve it,but I haven't any idea to make it stable and cheaper.

I think there are giants in forums,let's talk about it .

Do you even have any idea what a 4X225 watt amp can do in a car
and BTW TAS 5630 is a 1X600w chip=2X300w=4X150w. How did you got this magical figure 4 X 225W

Double chip,mean two chip in one amp,I have redraw our schematic for it ,we want make dc-dc and class d with two modules,so the dc-dc can be fitted near battery,and amp have little dimension and fit anywhere easily.

See Rod Elliott's DIY pages for regulated SMPS

Push Pull topic for regulated SMPS make easily,but light load noise darn it。I have to try boost circuit .

great idea..hope you can finish your TAS5630 car amp..

We are developing new modules of DC/DC+TAS5630 modules now,it can be fitted near speaker in the car ,easlily used ,connect +12v to DC INPUT,connect orignal speaker line to signal input,and connect speaker to module speaker out,it can deliver out 1*300W/2ohm/mono or 2*150W/4ohm/ stereo.10cm*10cm*3.5cm dimension.

.

Efficiency of a class ab amp is around 60%.

60% of power into speaker and 40% into the heatsink.

Class D is much better around 80-90%.

Usually car speakers have 2 - 4 ohm, I think a single TAS5630 will cut it. SE mode can handle 2ohm.

I would really like to see this chip in a head unit tho. May be not full power but around 100W++ X 4@4ohm. It will be the most powerful head unit ever.
