DC 6-24V to 5V 3A Step Down Buck Converter Module with USB

Overview

This is a non-isolated step-down buck converter module efficiently steps down DC 6V-24V to a stable 5.1V-5.2V output, making it ideal for powering USB devices, microcontrollers, Arduino, and other electronics. Featuring synchronous rectification, it ensures high efficiency, reaching up to 97.5% conversion efficiency under optimal conditions (6.5V input to 5V at 0.7A). The module operates at a 500KHz switching frequency, ensuring fast and stable power conversion with a low 10mV output ripple, reducing noise for sensitive electronics.

Designed for industrial-grade performance, this buck converter functions reliably within a -40°C to +85°C temperature range, though higher ambient temperatures may slightly reduce output power. The module is equipped with multiple protection features, including overvoltage protection via a 300W TVS clamp, short-circuit protection, and reverse polarity protection through an integrated diode. Additionally, an input fuse (1.5A) enhances safety, preventing excessive current draw. A red LED indicator provides a clear visual confirmation of active voltage output.

This converter supports a maximum output current of 3A, with load regulation of ±1% and voltage regulation of ±0.5%, ensuring stable power delivery. Its dynamic response speed is optimized at 5% within 200µS, minimizing voltage fluctuations under varying loads. The module has a static current draw of just 0.85mA, making it energy-efficient for battery-powered applications.

For easy integration, the module features input terminals pads for input connections and a USB output port for direct plug-and-play compatibility. It is ideal for DIY electronics projects, IoT applications, industrial automation, and automotive power solutions.
