The Adafruit 12V Bias Voltage Boost Converter utilizes the TI TPS61040 mini-booster to produce a 12V DC from just 3V input. This widely-used chip is often found in our OLED boards, providing essential 12V bias voltage for display functionality. Additionally, this converter can be used for various purposes, such as powering LED string backlights or re-programming FLASH and EEPROM memories.
This board is not suitable for high-powered devices such as solenoids, motors, or long analog LED strips, as it can only provide a maximum output of 40mA. However, it is a convenient option for supplying a small amount of current when a separate 12V supply is not available and the board already has 3.3 or 5V.
The Adafruit 12V Bias Voltage Boost Converter - TPS61040 comes with a fully assembled breakout, including the TPS61040 and necessary passive components. Simply provide 2 to 6V DC on the IN and Ground pins, and the 12V output pin will provide a stable output. To disable the output, pull the Enable pin low.
