It’s less than one watt of power - a tiny boost converter and a mosfet is all you need - no transformer or relay necessary - it takes less than a square inch of board space.
- dotancohen 5y agoI didn't realize it was that low - I thought it was a few amps. And even a single amp multiplied by 80 volts is far beyond what I would pump through typical hobby mosfets used with e.g. an Arduino or Raspberry Pi. By yeah, if it's just a watt, that's going to be on the order of tens of milliamps at 80 volts. It probably wouldn't even need a heatsink.
