The Adafruit 12V Bias Voltage Boost Converter uses the TI TPS61040 to generate 12V DC from as little as 3V input. This compact breakout is ideal for generating the bias voltage needed by OLED displays, LED string backlights, and FLASH/EEPROM reprogramming — without requiring a separate 12V supply.

With a maximum output of approximately 40mA, this board is designed for low-current applications where a small amount of 12V is needed alongside an existing 3.3V or 5V supply. An Enable pin allows you to disable the output when not in use.
