What parts of the microboost driver actually crate the heat? It's the little black chip on the back next to the coil right? (I'm pretty sure this is a FET, am I right?)
If you have any old xbox360's lying around, the RAM heasink pads on the underneath of the board are made of a heat conductive gel, which when pressed will mold itself to the various parts on the microboost, you can then heatsink the other side.
you need more than thermal epoxy, you need something to put on the other side of the epoxy.
I tested it tonight and was rather surprised. At 1A the little FET gets hot, but the pot does too. The coil and some resistors get warm, but nothing alarmingly warm.
I'll be making up a heatsink to sit over the FET at least, I think the pot should be ok if it gets warm.
