XL4016 High Power 8A Buck Module DC-DC Voltage Regulator ICs XH-M405

XL4016 High Power 8A Buck Module – DC-DC Adjustable Step-Down Voltage Regulator XH-M405 The XL4016 8A Buck Converter Module XH-M405 is a high-power DC-DC adjustable step-down voltage regulator designed to convert a higher DC input voltage into a lower, stable DC output voltage. It is suitable for powering Arduino boards, ESP32 projects, LED systems, motors, DIY electronics, battery-powered applications, and other projects that require adjustable DC voltage. The module uses the XL4016 switching regulator IC and features an adjustable output voltage with high current capability. Its compact design and screw terminals make it convenient for prototyping, electronic projects, and power supply applications. Specifications Module: XH-M405 XL4016 Buck Converter Type: DC-DC Step-Down (Buck) Converter Regulator IC: XL4016 Input Voltage: DC 4–38V Output Voltage: Adjustable approximately 1.25–36V DC Maximum Output Current: Up to 8A* Recommended Continuous Current: Lower than maximum rating depending on cooling and operating conditions Conversion Type: Step-Down Adjustment: Multi-turn potentiometer Efficiency: Up to approximately 96% depending on input/output conditions Switching Frequency: Approximately 180kHz Protection: Over-temperature and current-limit protection Connection: Screw terminal Application: Arduino, ESP32, LED, motors, DIY power supplies and electronics projects Features High-current 8A-class DC-DC buck converter Adjustable output voltage Wide input-voltage range High conversion efficiency Suitable for high-power electronic applications Screw terminals for easy wiring Compact and easy to install Useful for battery, LED, motor and embedded-system projects Applications Arduino and ESP32 power supplies LED lighting projects DC motor power control Battery-powered equipment DIY adjustable power supplies Electronics prototyping Industrial control projects Robotics and automation projects Note: The 8A figure is a maximum module rating, not necessarily a guaranteed continuous output under all conditions. For high-current operation, adequate heatsinking and airflow are important. Also, this is a buck/step-down converter, so the output voltage must be lower than the input voltage.
