It is often needed to have a bipolar power in audio applications, but it's hard to do when your device is portable. This project aims to design a bipolar power supply capable to deliver at least 150mA at both +12V and -12V buses.
- it can work in a boost configuration from just 2V in.
- it can output a negative voltage.
- it has a fixed output voltage of 12V or 5V.
- it has a built-in configurable low-battery detector.
I'm going to buy a few of these and try to build something. The typical application in a datasheet looks straightforward, so I don't even need to change it.
As a sidenote, I also found a very cool 4xAA battery holder made by Bulgin. It's quite expensive, but can be conveniently installed in a DIY enclosure.
very interested in this project, did you get anywhere ? I have made other power supplies with LT series IC's and found they work well. I used one to make 48v phantom power from 12vdv.
