Mini-360 DC-DC Buck Converter Adjustable 4.75-23V to 1-17V 3A Module

🔧 Mini-360 DC-DC Adjustable Buck Converter Module | AuscomTech

The Mini-360 is an ultra-compact non-isolated DC-DC step-down converter designed to reduce a higher DC input voltage to a lower adjustable output voltage.

It uses synchronous rectification with an integrated power inductor and adjustable potentiometer, providing efficient voltage conversion in space-limited electronics projects.

Suitable for powering microcontrollers, sensors, embedded circuits and other low-voltage devices from DC power sources within the specified operating range.

⭐ Key Features

• Adjustable Output – onboard potentiometer allows the output voltage to be set from 1.0V to 17V.
• Wide Input Range – operates from DC 4.75V to 23V.
• Synchronous Rectification – designed for efficient DC voltage conversion with up to 96% stated maximum efficiency.
• Compact Design – ultra-small module suited to projects where PCB space is limited.
• Integrated Power Inductor – compact molded inductor helps reduce overall module size.
• High Switching Frequency – operates at approximately 340kHz.
• Reverse Connection Protection – supplier specification indicates reverse-polarity protection.
