Uses the original XL4016 chip for reliable power DCDC conversion with a switching frequency around 180K Input: DC up to 40V. Exceeding this limit may damage the module Output current: up to 8A. For longterm use, it is recommended to stay under 5A Efficiency: up to 95% conversion efficiency to minimize heat and waste Design and performance: compact DCDC module with strong power handling and efficient operation for demanding loads Compatibility and application: suitable for integrating into power supply projects, automotive, solar, and other battery or DC power systems that require stable DC regulation Use scenarios Build or upgrade a portable power supply that accepts 40V DC input and delivers regulated current DC to your loads while minimizing heat Use in solar or battery systems to convert higher voltage sources to a reliable DC rail for equipment under load, with efficiency Implement in automotive or industrial projects that require converting 12–40V DC sources to regulated power for controllers, sensors, or other electronics Notes Do not exceed the 40V input limit to prevent damage The 8A maximum is the absolute limit; for extended service life, operate at or below 5A where possible
