A step-down converter module that allows you to reduce the input voltage from 12.2–36 V to a stable 12 V, ensuring high efficiency thanks to SMPS technology. A maximum output current of 600 mA allows you to power microcontrollers, IoT modules, and other electronic systems. The device is equipped with short circuit and overheating protection and offers very low quiescent current. Pololu 5597
The voltage converter module is a step-down (buck) converter designed to reduce an input voltage from 12.2 V to 36 V down to a stable 12 V output. Thanks to its switch-mode power supply (SMPS) design, it provides significantly higher efficiency than traditional linear regulators, especially when there is a large difference between the input and output voltages. The maximum continuous output current is 600 mA, making it suitable for powering a wide range of popular electronic circuits, microcontrollers, and communication modules. The device operates at a switching frequency of 1.1 MHz under standard loads and automatically reduces the frequency at light loads to further improve energy efficiency. The regulator features a very low quiescent current – below 0.01 mA across most of its operating range – making it an ideal choice for battery-powered applications.

The converter includes built-in short-circuit and overtemperature protection, ensuring stable and safe operation under all conditions. Its compact design allows for easy integration into space-constrained projects. The board features three pins: VIN (input voltage), GND (ground), and VOUT (output voltage), spaced at 2.54 mm for full compatibility with breadboards and prototyping connectors.
Thanks to its high efficiency and stable performance, this module is ideal for microcontroller-based projects, IoT systems, portable devices, and any other application requiring reliable voltage conversion. It combines compact size, high performance, and reliability, offering an excellent price-to-performance ratio.
