Description  Mini DC-DC 4.5-24V to 0.8-17V 3A Step Down Power Supply Module Voltage Buck Converter Adjustable 97.5% 1.8V 2.5V 3.3V 5V 9V 12V The Mini DC-DC Step Down Buck Converter is a high-efficiency power supply module designed to step down voltages from 4.5V–24V to a stable 0.8V–17V output. With a peak current capacity of 3A and conversion efficiency up to 97.5%, this module is ideal for hobby electronics, Arduino projects, robotics, and embedded systems. Key Specifications Input Voltage: DC 4.5V–24V Output Voltage: Adjustable 0.8V–17V or fixed values (1.8V, 2.5V, 3.3V, 5V, 9V, 12V) Output Current: Peak 3A, continuous 2A recommended Efficiency: Up to 97.5% Temperature Range: -40℃ ~ 85℃ Enable Pin (EN): High = Work (2–5V), Low = Off (~0V) Features and Benefits Ultra-compact design for easy integration Adjustable or fixed output for flexibility High conversion efficiency minimizes heat Reliable performance in DIY and professional projects Supports a wide range of power applications Applications This DC-DC buck converter module is commonly used in: DIY mobile power banks Arduino and Raspberry Pi projects Battery-powered monitoring systems RC cars, toys, and robotics Automotive electronics Communication devices How to Use Output Voltage This module can work in adjustable voltage mode (default) or fixed output mode: Adjustable Mode: Use directly after powering. Fixed Voltage Mode: Cut the wire and solder pads at the required voltage position: 12V → solder 12V pads 9V → solder 9V pads 5V → solder 5V pads 3.3V → solder 3.3V pads 2.5V → solder 2.5V pads 1.8V → solder 1.8V pads ⚠️ Important: Input voltage must always be greater than output voltage (step-down only). Avoid reverse polarity to prevent damage. Package Includes 1 x Mini DC-DC Buck Converter Module (3A)
