## Description

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. Adafruit 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.

### Features

- The TPS65131 can generate positive and negative voltages simultaneously
- Adjustable voltage ranges: +6V to +15V and -6V to -15V, these are somewhat approximate because the trimmer pot can vary, you may find +/-0.5V variance on the bookend values
- Input voltage: 3 to 5.5V
- Output current: 150mA from each rail (assuming +12/-12V from 4.5V input). So not good for a motor, best for biasing or powering analog/digital electronics
- Compact breadboard-friendly design with mounting holes and two trimmer pots
 
Adafruit initially designed this to generate a -12V bias voltage on an Apple \]\[ disk drive, but you could definitely use it for synthesizers/modulars, TTL logic or op-amps that want a wide power supply, biasing LCDs or OLEDs, as well as other uncommon voltages. The trimmers let you tweak the outputs so you could get +6V and -12V or +12 and -8V.
