Product Details :

The Electroboat Mini 360 Step-Down Buck Converter Power Module is one of the smallest high-efficiency DC-DC step-down voltage regulators available. Utilizing the MP2307DN integrated controller, this module employs synchronous rectification technology to achieve efficiency levels up to 96% while keeping heat generation to an absolute minimum.

Its miniature 17mm × 11mm footprint makes it an ideal replacement for bulky traditional linear regulators (like the 7805 or LM317) in space-critical applications. It features an onboard multi-turn potentiometer for precise output voltage adjustment between 1V and 17V. Built-in cycle-by-cycle over-current protection and 160°C thermal shutdown ensure safe operation under varying load conditions.

Key Features and Benefits

Ultra-Compact Form Factor: Measures only 17mm × 11mm, enabling seamless integration into small enclosures and drone frames
Synchronous Rectification Technology: Delivers up to 96% efficiency, maximizing battery runtime in portable devices.
Wide Input & Output Range: Accepts inputs from 4.75V to 23V DC and delivers adjustable outputs from 1.0V to 17V DC
High Switching Frequency (340 kHz): Allows for low output ripple (~30mV) and smooth power delivery.
Integrated Circuit Protection: Includes thermal shutdown at 160°C and automatic over-current limiting.

How to Use

Connect Power Input: Solder your DC power supply wires (4.75V to 23V) to the IN+ and IN- pads.
Adjust Output Voltage: Before connecting your load/circuit, apply input power and use a digital multimeter to measure the voltage across OUT+ and OUT-. Turn the brass screw on the potentiometer counterclockwise/clockwise until you reach your target output voltage.
Connect Load: Turn off the power supply, then connect your microcontroller, sensor, or motor circuit to the OUT+ and OUT- solder pads.
Thermal Precaution: For continuous current loads above 1.5A, ensure proper ventilation or add a small heat sink to prevent thermal throttling.
