My TAS5630DKD PCB
 
1 Attachment(s)
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?

crazifunguy 23rd February 2012 05:28 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.

luka 23rd February 2012 05:34 PM

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

crazifunguy 23rd February 2012 05:39 PM

Fpwm is 400Khz for the 5630.

luka 23rd February 2012 05:41 PM

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