XL4016E1 300W 10A DC-DC Step Down Buck Adjustable Converter

The XL4016E1-based 300W DC-DC Step Down Buck Converter module delivers reliable, adjustable voltage and current regulation for high-power applications. Built around the XL4016 switching regulator, this module handles up to 10A continuous output (8A recommended) with up to 96% efficiency, low ripple, and excellent line and load regulation. Onboard multi-turn potentiometers allow fine, accurate adjustment of both output voltage and current. The integrated heat sink enables sustained high-power operation without thermal throttling.

Operates in both Constant Voltage (CV) and Constant Current (CC) modes, making it ideal for battery charging, LED driving, and custom bench power supply applications.
