This dual-USB step-down buck converter accepts 8–32V DC input and delivers a regulated 5V output at up to 3A across two USB Type-A ports simultaneously. With over 85% conversion efficiency and built-in reverse-connection and overload protection, it provides a compact and reliable way to power USB devices from a higher-voltage source.

If the current on either output port exceeds 3.5A, the module automatically shuts off to protect connected devices.
