The DC to DC 6–18V to 5V USB Output Step Down Power Charger Buck Converter is a high-efficiency voltage regulator module designed to convert higher DC input voltages into a stable 5V output for powering and charging USB-compatible devices. It is ideal for applications where a battery, vehicle, or DC power source needs to be safely stepped down to USB voltage levels.
Supporting an input range from 6V to 18V, this buck converter is suitable for 12V and 9V systems, commonly found in automotive electronics, solar setups, battery packs, and embedded systems. The regulated 5V USB output allows direct charging of smartphones, power banks, microcontrollers, GPS units, and USB-powered devices.
The module uses efficient switching regulation, which reduces heat generation and improves energy efficiency compared to linear regulators. Its compact design makes it easy to integrate into DIY projects, power management systems, and portable devices.
