12PCS MP1584 DC-DC Power Supply Module 3A for

Feature Highlights: 1. Ultra-Compact Design: Perfect for applications where space and weight are critical, such as DIY portable power banks, monitoring systems, children's toy cars, camera setups, vehicle electronics, communication devices, and model aircraft. 2. Wide Voltage Range: Input voltage from 4.5V to 28V, with an adjustable output from 0.8V to 20V. Easily set your desired voltage using a screwdriver to adjust the built-in potentiometer while monitoring with a multimeter for precise calibration. 3. High Efficiency & Stable Output: Delivers up to 3A output current with a high conversion efficiency of 92% and low output ripple (under 30mV), ensuring reliable and clean power for your sensitive electronics. 4. Built-in Protection & Durability: Features adjustable current limiting with a fixed 3A limit. Constructed from quality PC material and metal components in a green/black finish, it operates reliably in temperatures from -45°C to +85°C. Please avoid reverse polarity, short circuits, and very light loads (below 10% of rated power) to prevent damage. 5. Easy to Use & Install: No complex wiring needed. Simply connect, adjust, and it's ready to go. The compact size (22mm x 17mm x 4mm) makes it easy to integrate into various projects. Product Details: This ultra-small DC-DC buck module is a versatile and efficient step-down converter. It allows you to precisely adjust the output voltage for a wide range of low-voltage applications. The board is designed for stability and durability, with built-in current limiting for added protection. Its high switching frequency and efficient design minimize heat and power loss. Ideal for hobbyists and professionals needing a reliable, adjustable power solution in a tiny footprint.
