Product Description
The XH-M401 DC-DC Step Down Buck Converter Module is a high-performance adjustable voltage regulator designed to efficiently convert a higher DC input voltage into a lower, stable DC output voltage. Powered by the XL4016E1 PWM buck converter IC, this module supports an input voltage range of 4V to 40V DC and provides an adjustable output from 1.25V to 36V DC with up to 8A peak current and 200W maximum output power.
This module features high conversion efficiency (up to 94%), making it ideal for reducing power loss and heat generation. Its built-in aluminum heatsinks ensure reliable thermal management during high-current operation, while the onboard potentiometer allows smooth and accurate output voltage adjustment.
The XH-M401 is widely used in DIY electronics, battery charging systems, LED lighting, automotive power supplies, robotics, industrial control systems, communication equipment, and embedded electronic projects requiring stable and efficient DC voltage regulation.
