DC-DC Step Down Power Supply Ultra-small Size Module 3A Adjustable Buck Converter

The Mini MP1584 DC-DC Adjustable Buck Converter is a compact, high-performance step-down voltage regulator capable of converting an input voltage between 4.5V and 28V into an adjustable output range from 0.8V to 20V. It uses the MP1584EN switching regulator, which integrates a high-voltage power MOSFET and includes safety features like soft start, thermal shutdown, and under-voltage lockout (UVLO) for robust and reliable performance.

Thanks to its small size, light weight, and low power consumption, it is suitable for a wide range of portable and embedded applications, such as drones, RC models, DIY electronics, and robotics.
