My TAS5630DKD PCB

ngen33r · 2012-02-21 6:39 am

I have been doing a lot of reading about this Class D chip. I decided that the EVM was a little expensive and I was not a big fan of the EVM pcb. I had pleanty of free time so I decided to take a shot at making my own pcb.
The pcb was made in Eagle and checked with Viewplot.

It pretty much follows the EVM design with only a few differences.
Minor movement of components
Mounting for Intel P4 heatsink
Screw Terminals vs RCA & Banana Plugs

Please have a look at the layout and give feedback. Thank You.

I got to say, I would like to see this get builded

After checking the board and schematic a few more times I will order 5 prototype pcb's and assemble. Hopefully it will work with good results. I made sure that the SMT inductors had very high saturation currents (21A). Hopefully the build will have good results.

can you post a link, which inductors are?

6.8uH? what freq will you be using?

ngen33r · 2012-02-23 6:28 pm

The default of Fosc is 4Mhz. The EVM uses the default master. Do you see any issues with this? The PCB has the option to add a resistor to change the frequency.

wait what? switching freq. won't be anywhere near that, you know that right?
with similar IC, tas5161 its around 380k, if you use tas3308 as I would

ngen33r · 2012-02-23 6:39 pm

Fpwm is 400Khz for the 5630.

luka · 2012-02-23 6:41 pm

ok, that is good freq., I would start there and see if its ok for you

I may need some adjustments due to the larger heatsink and extended traces in the current path, but the interference should be fairly low. After testing I would also like to make a 2.1CH and 4CH revision. Theis BTL/PBTL setup will be tested with a PA setup and also a home. The SMPS will supply 48V@450W.

cool, can't wait to see progress

ngen33r · 2012-03-15 10:25 pm

Been a little busy with work but I managed to order 2 PCB's. They should be here in a couple weeks and if they look good I will order some components. I will upload high rez scans when I get them.

sounds good

ngen33r · 2013-02-26 1:33 am

Well after life kicked my *** for several months, I am back at it. The PCB needs some updates and I need to triple check the schematic again but I still plan to make this thing look and sound awesome.

Hi, I also designed a pcb for the tas5630(b) and would love to see your assembled product. Please keep us up to date.
