2.1A DC8-80V to 12V High Voltage Buck Conversion Module

This 2.1A DC 8–80V to 12V Buck Converter Module is a high-efficiency step-down power supply designed for stable 12V output in high-voltage environments. Built with input reverse polarity protection and TVS overvoltage protection, it ensures reliable and safe performance. The high-frequency filter capacitor and 100uH high-Q inductance improve output stability while maintaining up to 93% conversion efficiency.

With built-in overcurrent, over-temperature, and short-circuit protection, this module is ideal for electric motorcycles, CCTV systems, routers, and industrial equipment. Operating at 100KHz with low quiescent current of about 2.5mA, it supports long-term battery-powered applications. Compact, lightweight , and durable, this DC-DC converter performs efficiently across a wide temperature range from -40°C to 85°C, making it suitable for demanding applications.
