Whether you're powering a portable device or building your own adjustable power supply, this module ensures reliable performance even in low-voltage scenarios. With its ability to output 5V, 9V, or 12V, it’s Suitable for precision instruments and DIY projects alike. 【Industry-Leading Performance】 - Power delivery with our 10A switching current, delivering up to 30W of output power. Whether you need to charge high-powered devices or run demanding electronics, this module delivers consistent and robust performance every time. Its exceptional efficiency ensures minimal energy loss during operation. 【Exceptional Energy Efficiency】 - Our module boasts 91.2% conversion efficiency, ensuring that every watt counts. The ripple is as low as 34mVpp when powered by a 18650 battery, reducing noise and improving overall system stability. For those who prioritize precision and reliability. 【Advanced Design & Safety Features】 - Equipped with tantalum capacitors, this module offers an ultra-low ripple of just 20mVpp, significantly lower than s (>80mVpp). Additionally, the PFM mode quiescent current is only 200μA. To ensure safety, always use a heatsink when output exceeds 15W to prevent overheating and potential damage. 【Versatile Applications】 - Designed for flexibility, this module is suitable for a wide range of applications, including DIY adjustable power supplies, precision instruments, and more. Its PWM/PFM pad-free switching capability allows integration into various systems. With its compact size (≤24×15mm), it fits easily into tight spaces without compromising performance.

WARNINGS:
Insufficient heat dissipation = burning! Output >15W must be installed with heat sink (size ≤24×15mm).
High-voltage differential output is strictly prohibited: Setting voltage should be ≥ input voltage +2V (e.g. input 5V→output ≥7V).
The quality of the input power supply determines the ripple: poor quality power supply leads to ripple soaring 100% +!
