DCDC StepDown Converter Module Key benefits Wide input range lets you power 1.25–30V devices from common highervoltage sources (DC 6.5V–60V). output current capability (up to 10A) supports powerhungry loads and small motors, multiple LEDs, or compact bench supplies. Simple, onboard adjustment with a screwdriver makes voltage tuning quick and repeatable for prototyping and repairs. Compact PCB module design integrates easily into DIY projects, test rigs, and retrofit applications. What it does (function) Converts a higher DC input voltage down to a continuously adjustable lower DC output voltage. Output range: 1.25V to 30V adjustable. Input range: DC 6.5V to 60V (input must be higher than desired output; no boost capability). Maximum output current: 10A. How it solves problems Enables safe operation of lowervoltage electronics when only highervoltage supplies are available. Provides a simple way to create an adjustable power source for testing, tuning, or powering modules without changing batteries or supply rails. Avoids the need for multiple fixed regulators by offering a single, adjustable solution covering a broad voltage and current range. Key attributes Function: DCDC stepdown (buck) converter; continuously adjustable output. Compatibility: Works with DC supply sources between 6.5V and 60V; suitable for devices that require 1.25V–30V and up to 10A. Performance: Up to 10A output current; stable adjustable voltage across the specified range. Form: Compact PCB module designed for easy integration into DIY and professional setups. Adjustment: Blue potentiometer screw for fine tuning. How to use Connect an appropriate DC power source (6.5V–60V) to the module input. Ensure input voltage is higher than your target output voltage (module cannot boost). Use a mini screwdriver to turn the blue potentiometer: Clockwise to increase output voltage. Counterclockwise to decrease output voltage. Monitor the output with a multimeter while adjusting to reach the required voltage. Verify connections and rated current handling for your load before continuous operation. Practical applications (examples) Bench power supply for electronics prototyping and component testing. Powering LED arrays, small motors, and sensors that require an exact lower voltage from a highervoltage source. Converting vehicle or battery pack voltages (e.g., 12V, 24V, or higher) down to the voltages needed by control boards, modules, or charging circuits. Important notes This module only steps down voltage; it cannot increase (no boost function). Always ensure the input voltage is greater than the target output voltage. Monitor voltage and current during setup to prevent damage to loads or the module.
