## Description

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. Key Features TPS61040 Boost Converter – Generates 12V DC from 2–6V input ~40mA Max Output – Suitable for bias voltage and low-current 12V applications Enable Pin – Pull low to disable the 12V output Compact Breakout – Pre-assembled with all required passive components Ideal For OLED display bias voltage generation LED string backlight driving FLASH/EEPROM reprogramming voltage Projects needing a small 12V supply from a 3.3V or 5V source Package Contents 1× Adafruit 12V Bias Voltage Boost Converter breakout (assembled) 1× Header strip Warning: This board is not suitable for high-power loads such as solenoids, motors, or long analog LED strips. Maximum output is approximately 40mA. Specifications Boost Converter – TI TPS61040 Input Voltage – 2–6V DC Output Voltage – 12V DC Max Output Current – ~40mA Resources TPS61040 Product Page (Texas Instruments)
