MP1584EN DC-DC BUCK Adjustable Step Down Module
Core Functionality Advanced Regulation: Utilizes the MP1584EN high-frequency switching regulator and an integrated high-voltage power MOSFET for reliable performance. Smart Protection: Built-in Soft Start, Thermal Shutdown, and Under-Voltage Lockout (UVLO) protect both the module and your connected devices from electrical stress. Light Load Efficiency: Features a Pulse Skipping Mode that maintains high efficiency even when your project is drawing very little current. Stable Output: Optimized for use with ceramic capacitors, ensuring a steady voltage with an output ripple of less than 30mV. Technical Specifications Parameter Specification Input Voltage Range 4.5V to 28V Output Voltage Range 0.8V to 20V (Adjustable) Maximum Output Current 3A (Peak) / 1.8A (Typical) Switching Frequency 1MHz (Typical) / 1.5MHz (Max) Efficiency Up to 96% Operating Temperature -50°C to +85°C Dimensions 22mm x 17mm x 4mm Common Applications Robotics & DIY: Powering Arduino, Raspberry Pi, AVR, or ARM-based projects. RC Vehicles: Ideal as a Universal Battery Elimination Circuit (UBEC) for 2S-6S LiPo packs in planes and drones. Portable Gear: Lightweight power supplies for mobile communication equipment and sensors. Prototyping: Adjustable breadboard power supply for testing various components. Important Setup Note: Always use a voltmeter to measure and set the output voltage by turning the onboard potentiometer before connecting the module to your target device.
