Adafruit TPS65131 Split Power Supply Boost Converter touch screen with speaker Pastel PinkNeed 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
