Adafruit TPS65131 Split Power Supply Boost Converter

Need those tricky split-rail voltages for your vintage electronics? The Adafruit TPS65131 Split Rail Boost Converter generates both positive and negative voltage rails from a single 3-5V input. This makes it great for mimicking or replacing a transformer-based power supply or something that needs negative bias. We kept the design compact, and it even has adjustable output pots, so you can tune the voltages from about +6~+15VDC and -6~15VDC. Perfect for use with audio or retro projects now that transformer supplies are hard to get, or if you want to have something that could run on battery or USB.
