My team and I are trying to power a sensor. We need to get -5.5 volts and were not too familiar with making or acquiring negative voltages. So it doesn't have to be a 12 volt. Ultimately we'd like to use one battery and split out different rails from it to power two different devices.
seemed to be insightful. There are solutions out there to acquire negative voltages. We are looking for cheap and simple and the "Split rail" option looks like a path.
But upon looking at a few online there seems to be poor efficiency at the 3 mA load levels.
Could anyone point me in a good direction of research for a good solution to get a negative 5.5 voltage from a positive voltage at a very low amp level (3mA).
Please and thank you from Chuck a ELE student, having fun researching for senior project.
