Meet the MP1584EN Mini DC-DC Step-Down Module, a compact and highly efficient power regulator perfect for your electronics projects. This buck converter takes a higher input voltage and safely steps it down to a lower, adjustable output voltage. Its small size and high switching frequency make it an ideal replacement for older, bulkier regulators like the LM2596.

Whether you're powering an Arduino, creating a custom battery-powered device, or need precise voltage for your DIY project, this module delivers stable and reliable performance.

Key Features

• High-Efficiency Conversion: With up to 92% conversion efficiency, it minimizes power loss and heat generation.
• Wide Voltage Range: Accepts an input voltage from $4.5V$ to $28V$ and provides an adjustable output from $0.8V$ to $20V$.
• Adjustable Output: Features an onboard potentiometer for fine-tuning the output voltage to your exact needs.
• Compact & Lightweight: Measuring only $$\begin{gathered} 22mm \\ times17mm \end{gathered}$$, it fits easily into space-constrained projects.
• High Switching Frequency: A $1.5MHz$ switching frequency allows for smaller external inductors and capacitors, contributing to its miniature size.

Common Applications

• DIY mobile power supplies
• Powering microcontrollers like Arduino, ESP32, and Raspberry Pi
• Battery-powered cars, drones, and robotics
• LED lighting drivers
• Telecommunication and networking equipment
• Any project requiring efficient voltage reduction
