Mini-360 Ultra Compact DC-DC Buck Converter Module with Synchronous Rectification 17x11mm

The Mini-360 represents a particularly space-efficient solution for DC voltage conversion requirements in electronics projects and compact device designs. Measuring just 17×11×3.8mm, this synchronous rectification buck module converts higher DC input voltages to lower regulated outputs while maintaining high efficiency in a minimal footprint. With an input range of 4.75V to 23V and adjustable output from 1.0V to 17V, it accommodates various power supply scenarios from battery-powered devices to embedded system voltage regulation. The module's 96% maximum conversion efficiency and 340KHz switching frequency make it suitable for applications where both size and power efficiency matter.

Features and Construction

This buck converter module employs several design approaches that contribute to its compact dimensions and operational characteristics. The synchronous rectification architecture differs from traditional diode-based designs by using active switching elements, which reduces power loss during voltage conversion. The integrally moulded power inductor combines the magnetic core and winding into a single compact component, saving board space compared to discrete inductor solutions.

Material and Build

The module utilises a standard PCB substrate with green solder mask finish, populated with surface-mount electronic components arranged to minimise the overall footprint. The integrally moulded power inductor represents a key space-saving element, combining the magnetic core and winding structure into a single compact package. This construction approach, along with the synchronous rectifier control chip and carefully selected passive components, enables the module's 17×11mm dimensions while maintaining the specified electrical performance parameters.

Size and Practical Fit

With dimensions of 17mm in length, 11mm in width, and 3.8mm in height, the Mini-360 occupies minimal board space, making it suitable for integration into portable electronics, embedded systems, and projects with severe space constraints. The small footprint allows placement in tight locations where traditional larger converter modules would not fit. The low profile of 3.8mm enables use in slim device designs, while the standard 0.1" pin spacing (though not explicitly stated but typical for such modules) facilitates connection to breadboards, prototype boards, or custom PCBs.

Uses and Placement

The Mini-360's specifications support various applications requiring voltage step-down conversion in limited-space environments. Its operational characteristics make it appropriate for both prototyping scenarios and integration into finished products where reliable voltage regulation in a small package is needed.

Event or Professional Use

In professional electronics development and manufacturing contexts, this module can serve as a compact voltage regulator for embedded systems, IoT devices, sensor nodes, and portable instrumentation. The wide 4.75-23V input range accommodates various power sources including 5V USB, 12V adapters, and multiple-cell battery packs. The adjustable 1.0-17V output supports microcontrollers, sensors, displays, and other components requiring specific voltage levels. The module's ±0.5% load regulation and ±2.5% voltage regulation provide sufficient stability for many digital and analogue circuits.

Everyday Home Use

For electronics hobbyists and DIY enthusiasts, the Mini-360 offers a compact solution for powering Arduino projects, Raspberry Pi accessories, LED lighting installations, and custom electronics builds. The small size allows integration into finished projects without adding significant bulk, while the adjustable output enables compatibility with various components requiring different voltage levels. The module can step down higher voltages from wall adapters or battery packs to the specific voltages needed by project components, potentially reducing the need for multiple dedicated power supplies.

Benefits and Buying Value

The Mini-360 provides several practical advantages stemming from its design specifications and construction approach. These benefits relate primarily to space efficiency, operational flexibility, and performance characteristics relevant to voltage conversion applications.

Reuse and Low Maintenance

As a solid-state electronic module without moving parts, the Mini-360 requires no routine maintenance beyond appropriate operating conditions. The module can be reused across multiple projects or prototypes, with its solderable connections allowing secure mounting in various configurations. The specified -40°C to +85°C operating temperature range supports use in environments with temperature variations, though adequate ventilation or heat sinking should be considered when operating near maximum current ratings.

Why Choose This Product

The Mini-360 stands out for applications where board space is severely limited yet reliable voltage conversion is required. Its 17×11mm dimensions represent a significant size reduction compared to many standard buck converter modules, while still providing a useful 3A maximum output current and wide voltage adjustment range. The synchronous rectification design contributes to the 96% maximum efficiency rating, which can reduce power loss and heat generation compared to less efficient converter topologies. For projects needing compact voltage regulation without sacrificing performance parameters, this module offers a balanced combination of size, capability, and efficiency.
