The 6–26V to 5V DC-DC Buck Converter 1A USB Output Module is a step-down voltage regulator designed to convert a higher DC input voltage into a stable 5 V DC output via a USB interface. It supports an input range of 6–26 V DC and provides regulated output suitable for powering low-power USB devices. With high conversion efficiency above 93%, it minimizes energy loss during voltage conversion under typical load conditions. The module is commonly used in embedded systems, DIY electronics, battery-powered projects, and automotive or industrial low-voltage power adaptation applications. Its compact form factor enables easy integration into space-constrained electronic assemblies.
