## Description

Quickly powers USB-C devices from 12-24V sources, car, batteries, or solar systems, providing stable 5V up to 3A, 15W. Efficient buck converter with up to 91% efficiency, featuring overcurrent, short circuit, and overheating protection, compact design for easy integration into DIY projects, boats, or mobile installations.
The buck step-down voltage module is designed to power devices with a USB-C port from higher voltage sources, such as 12V or 24V batteries. It accepts an input voltage in the range of 8 - 30 VDC and provides a stable 5V output through a USB-C connector, with a maximum current of 3A (15W), sufficient for charging mobile phones, tablets, Raspberry Pi devices, navigation systems, or other equipment powered via USB.
The converter uses a high-efficiency buck integrated circuit (up to 91%) and includes protections against overload, reverse polarity, short circuit, and overheating. Due to its small size, the module can be easily integrated into DIY projects, solar systems, boats, or used as a portable backup power source.
