## Description

The **Adafruit 12V Bias Voltage Boost Converter** uses Adafruit's new favorite mini-booster, the [TI TPS61040](https://www.ti.com/product/TPS61040), to generate a 12V DC from as little as 3V input. Adafruit use this chip a ton in Adafruit's OLED boards, to generate the 12V bias voltage needed for the displays to function. But there's probably many other times and reasons you may want a high-ish voltage, such as driving an LED string backlight or re-programming FLASH or EEPROM memories.

Note that this board *isn't* good for high power driving, like solenoids or motors or long analog LED strips. You can get about 40mA out max. But definitely easier than getting a separate 12V supply when just a small amount of current is needed and you've already got 3.3 or 5V on the board.

You get one fully assembled breakout with a TPS61040 and required passive components, and a small bit of header. Give 2 to 6V DC on the **IN** and **G**round pins. Then you'll have 12V on the 12V output pin. The **En**able pin can be pulled low to disable the output.
