At first we were working on a project about a portable stereo speaker but we had no good battery appropriate to our circuit. So, based on the LT1302 documentation, we designed this 2xAA power circuit to get 12V for the amplifiers.
This 12V power supply is based on the LT1302. It should be capable to power some Portable Stereo Speakers we are working on. With a theoretical 120mA output, it can power many things else.
