Pololu 12V Step-Up/Step-Down Voltage Regulator S18V20F12

The Pololu 12V Step-Up/Step-Down Voltage Regulator S18V20F12 is a versatile DC-DC converter that provides a fixed 12V output from a wide input voltage range of 6V to 30V. Using a buck-boost (SEPIC) topology, it can regulate the voltage whether the input is above or below 12V, making it ideal for battery-powered applications or systems with unstable input. It can deliver up to 2A of continuous current (depending on input/output conditions) and includes key protections such as reverse voltage protection, over-current limiting, thermal shutdown, and under-voltage lockout. This regulator’s efficiency, compact design, and reliability make it a strong choice for embedded systems, automotive electronics, and robotics requiring a consistent 12V power source.
