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.

• The TPS65131 can generate positive and negative voltages simultaneously
• Adjustable voltage ranges: +6V to +15V and -6V to -15V, with approximately ±0.5V variance
• Input voltage: 3 to 5.5V
• Output current: 150mA from each rail (assuming +12/-12V from 4.5V input); not suitable for motors, ideal for biasing or powering analog/digital electronics
• Compact breadboard-friendly design with mounting holes and two trimmer pots

Initially designed to generate a -12V bias voltage on an Apple ][ disk drive, this module is suitable for synthesizers, modular synths, TTL logic, op-amps requiring wide power supplies, biasing LCDs or OLEDs, and other uncommon voltages. The trimmers allow adjustment of outputs to configurations such as +6V/-12V or +12V/-8V.
