DC-DC Step Down Buck Converter (6~24V to 5V/16A)

This DC-DC step-down converter module is designed to provide reliable power conversion with high efficiency. It accepts a wide input voltage range from 6V to 24V and provides a stable 5V output, supporting up to 16A of current. The module is equipped with key features such as over-temperature protection (up to 125°C), output short circuit protection, and an output ripple noise of less than 20mV. Achieving conversion efficiency greater than 90% under typical conditions (12V input with 1-16A load), this module is ideal for applications that require a stable and efficient power supply, such as driving multiple motors or servos in robotics, high-power LED lighting systems, automotive electronics and DC-powered devices, smart robots, drones.

High Efficiency and Low Ripple

The module achieves a conversion efficiency of over 90% with a 12V input and 1-16A load, ensuring minimal energy loss. Its output ripple noise is maintained below 20mV, making it suitable for sensitive electronic devices and precision applications.

Robust Protection Mechanisms

Equipped with 125℃ over-temperature protection and output short-circuit protection, the module ensures reliable operation even under harsh conditions. These features safeguard both the module and connected devices from potential damage.

Enhanced Heat Dissipation

A thermal pad on the back of the module allows for soldering to a large copper area, significantly improving heat dissipation capabilities. This design ensures stable performance even during prolonged high-current operation.

The module features three control pins:
