Over the break I’ve been working on a driver board for the TBA6560, this is what I’ve got so far. It’s open source, although I won’t bother posting the files until it’s a bit more substantial, and I’ve made the PCB layout.
It’s a pretty simple circuit, the only tricky parts are figuring out values for certain parts. I got a lot of help form CNCzone, where there is an entire post on this chip. One of the important issues covered was that a low esr capacitor is needed across the 35v source. Setting the frequency is also a bit of a mystery.
