Source for heatsink on TDA1543 chips?

drjlo · 9th June 2008, 07:26 PM

I have 8 chips right now, which is pretty hot. I can hold my finger on top for maybe 2 seconds before I have to let go due to heat.

I plan to add 8 more chips in parallel, but I can't find any source for a good heatsink, preferably in copper. Anybody know a source, either for single heatsinks or longer ones to attach 2 chips?

You can try to contact Doede at www.dddac.de or www.dddac.com he sells very nice heatsinks.

I looked around re DDDac, but he seems to only offer vertical heatsinks for the stacked chips. As the photo shows, I need something on top of each chips, perhaps covering 2 chips together.
