I became intrigued with the 200W+ audio amplifiers on Amazon for $80 or so on Amazon. I did a little digging and found that some were based on a TI TPA3255 chip. I picked up a few MPN: TPA3255DDV and went to town. I basically lifted this schematic directly from the datasheet so it wasn’t like I had to get super creative, but it was fun dealing with power levels that I’m not used to.
This one worked on the first try, so you know something went very wrong. The difference is this time I don’t know what it was. Maybe that’s the definition of success.
