This DC-DC step-down converter module is designed to efficiently reduce a high input voltage (15-24V) to a stable 12V output, supporting up to 12A of current. The module offers high conversion efficiency (over 95%), with minimal ripple noise (under 50mV), making it suitable for power-sensitive applications. It also includes built-in protection features such as over-temperature protection (up to 125°C) and short circuit protection, ensuring the safe operation of both the module and connected devices.

High Conversion Efficiency

Achieves greater than 95% efficiency with 24V input and 1-12A load, minimizing energy loss and ensuring reliable power conversion for demanding applications.

Over-Temperature and Short Circuit Protection

Features over-temperature protection up to 125°C and output short circuit protection, safeguarding the module and connected devices from damage.

Thermal Management for High-Current Loads

A built-in thermal pad allows for enhanced heat dissipation when soldered to a larger copper area, providing improved performance under heavy load conditions.


The module features three control pins:

Pin and Dimension Diagram of DC-DC step-down converter module

Figure: Pin and Dimension Diagram of DC-DC step-down converter module

  • EN: Floating (open) to enable the output, connected to ground to disable the output. It can be controlled by a microcontroller's IO pin with a 1K resistor in series.
  • AGND: When control is needed from a microcontroller, connect a single ground point to this pad.
  • PGOOD: Outputs a high level (5V) when the output voltage is normal. Outputs a low level (0V) when there is an abnormal output voltage or a short circuit.
