Mini 360 DC-DC Adjustable Step-Down Power Supply Module (Ultra-Small Buck Converter)

When you need to step down a lithium battery pack or standard DC adapter to power 3.3-Volt or 5-Volt sensors, but traditional modules like the LM2596 are far too bulky, the Mini 360 step-down (buck) converter is the perfect solution. Barely larger than a postage stamp, this microscopic module takes input voltages ranging from 4.75 Volts up to 23 Volts and efficiently steps them down to a highly stable, adjustable output anywhere between 1.0 Volt and 17 Volts.

Despite its incredibly small size, the Mini 360 packs a serious punch. By utilizing synchronous rectification and an integrally molded power inductor running at a 340 kHz switching frequency, it achieves up to 96 percent conversion efficiency. This drastically reduces heat generation and allows it to comfortably deliver 1.8 Amps of continuous current (and up to 3 Amps peak) without requiring bulky heatsinks. It is the absolute favorite power module for drone builders, RC hobbyists, and custom IoT designers who need to hide a reliable power supply inside tiny 3D-printed enclosures or lightweight aircraft frames.

Key Features & Functional Advantages

• Microscopic Footprint: Measuring just 17mm by 11mm, it is one of the smallest step-down converters on the market, allowing it to be easily integrated into the tightest spaces.

• Synchronous Rectification: Uses advanced internal switching rather than older diode-based regulation, drastically reducing heat generation and maximizing battery life.

• Fully Adjustable Output: Features a miniature precision potentiometer. Using a very small screwdriver, you can carefully dial in the exact logic voltage your specific components require.

• Wide Input Compatibility: Safely accepts anything from standard 5-Volt USB power up to 12-Volt car batteries and 4S lithium-polymer (LiPo) drone batteries.

• Low Output Ripple: Delivers exceptionally clean DC power with extremely low high-frequency noise (typically under 30mV), ensuring sensitive microcontrollers and sensors operate flawlessly.

Perfect For

• Drones and RC Vehicles: The industry standard for taking a high-voltage LiPo flight battery and safely stepping it down to run 5-Volt flight controllers, receivers, and FPV cameras without adding unnecessary weight.

• Miniature IoT Devices: Hiding a dedicated 3.3-Volt or 5-Volt power rail inside tiny, self-contained remote sensor nodes and ESP8266 weather stations.

• Portable Battery Power: Replacing inefficient linear regulators in DIY battery-powered electronics to eliminate thermal throttling and squeeze every last drop of capacity out of the battery.

• Custom Enclosures: Any DIY electronics project where you have severely limited internal volume and cannot accommodate standard, bulky PCB power modules.
