Energy harvesting IC...

[ScaleRobotics]

Did you check the datasheet for your model?

It's talking about 3A 15.4V max at delta Tmax 66c @ 27c.

Ok, so I'm not sure how to interpret all that, but is it possible that you went over specs by going up to a 100c difference?

Thanks Robert,

I was working in the 100 degrees F range.
I don't really know which model mine has inside it. I probably would get more voltage at 150 degrees F difference. But in a real world scenario, it would be hard to produce this naturally I would think. Other than placing one side of it on my muffler or something .... and then I could just use the alternator.

Mine is better suited for building a 12 to 15 volt dc refrigerated cooler. I think that is what mine was originally built for. I bought mine at a surplus electronics store.
