Mini 360 DC Buck Converter Compact Synchronous Step Down Module 3A

The Mini 360 DC buck converter is a non-isolated synchronous rectification step-down module designed for space-constrained electronics projects. Its integrally moulded power inductor and synchronous control chip deliver up to 96% conversion efficiency while keeping the footprint remarkably small at just 17 x 11 x 3.8 mm. This makes it an excellent choice for battery-powered devices, voltage regulation in embedded systems, and any application where board space is at a premium.

Features and Construction

Built around a dedicated synchronous rectifier controller, the Mini 360 achieves higher efficiency than conventional diode-based buck converters, particularly at lower output voltages. The module uses a single-layer PCB with clearly labelled input and output pads for easy soldering.

Material and Build

The module incorporates an integrally moulded power inductor that reduces both size and electromagnetic interference. The green PCB has a compact layout with through-hole pads for input, output, and enable connections. All components are rated for operation between -40°C and +85°C.

Size and Practical Fit

With external dimensions of just 17 x 11 x 3.8 mm, the Mini 360 is one of the smallest adjustable buck converters available. It can be soldered directly into a prototype board or used with pin headers for removable connections, making it suitable for portable and handheld projects.

Uses and Placement

This converter is ideal for stepping down battery voltages to power microcontrollers, sensors, and other low-voltage logic. Its high efficiency helps extend battery run time compared to linear regulators.

Event or Professional Use

Engineers and hobbyists frequently use the Mini 360 in drone power distribution, robotics, and portable instrumentation where size and efficiency are critical. The module's low output ripple (30mV) makes it suitable for powering sensitive analogue circuits.

Everyday Home Use

For DIY electronics enthusiasts, this module simplifies creating custom power supplies from a bench supply or wall adapter. The adjustable output lets you power projects at 3.3V, 5V, 12V, or any voltage between 1.0V and 17V.

Benefits and Buying Value

The Mini 360 offers a practical balance of performance and size, making it a versatile addition to any electronics toolkit. Its synchronous rectification design reduces heat generation, so it can operate without bulky heatsinks in many low-current applications.

Reuse and Low Maintenance

Once configured, the module holds its output voltage without further adjustment. Its robust operating temperature range means it can be reused across multiple projects without degradation.

Why Choose This Product

If you need a high-efficiency voltage step-down in a tiny package, the Mini 360 delivers. It supports input voltages from 4.75V to 23V and outputs up to 3A (1.8A continuous) with load regulation of ±0.5% and voltage regulation of ±2.5%.
