MP1584EN DC-DC Step Down Converter Module

Here is a short description of the MP1584EN Ultra-Small DC-DC Buck Converter Module:

• What it is: An ultra-compact, high-efficiency step-down (buck) switching regulator board that converts a higher DC voltage down to a lower, stable DC voltage.

• Key Specs:

  • Input Voltage: 4.5V to 28V DC

  • Output Voltage: 0.8V to 20V DC (adjustable via an onboard miniature potentiometer)

  • Output Current: Up to 2A continuous, 3A peak (heatsink recommended above 1.5A–2A)

  • Switching Frequency: High frequency (up to 1.5MHz), allowing for small filter components and very low output ripple.

• Key Features: Extremely small footprint (much smaller than LM2596 modules), high efficiency (up to 92%+), and built-in thermal and over-current protection.

• Common Uses: Ideal for space-constrained projects powering Arduino, ESP32, Raspberry Pi, RC vehicles, and drones from higher-voltage sources like 9V, 12V, or multi-cell LiPo batteries.
