GCON Mini 360 Buck Converter 3A DC-DC Step-Down Module 4.75-23V to 1.0-17V 25 Pack

SKU CH-J4J0-P0XVR

Pack of 25 step-down modules converting 4.75-23V input to adjustable 1.0-17V output at up to 3A with 96% efficiency

  • Adjustable 1.0 V to 17 V output from a 4.75 V to 23 V input
  • Up to 3 A continuous current for low-power projects
  • 96 % peak efficiency reduces heat in compact builds
  • 340 kHz switching keeps ripple below 30 mV at no load
  • 25-module pack supports multiple DIY, LED or micro-controller designs

25-piece buck converter kit

This pack contains 25 Mini 360 step-down modules built around the MP2307 synchronous rectifier controller. Each board accepts a DC input from 4.75 V to 23 V and provides an adjustable output between 1.0 V and 17 V at up to 3 A. The compact form factor suits hobbyists, students and engineers building DIY power supplies, LED drivers, micro-controller projects or battery chargers.

Thermals, noise and power draw

Switching at 340 KHz, the modules reach a maximum efficiency of 96 percent and exhibit less than 30 mV ripple with no load. The integrally moulded power inductor helps keep the footprint small while maintaining synchronous rectification. At full 3 A output, additional heat-sinking is required to maintain stable operation and prevent thermal throttling.

What the pack changes for your workflow

Supplying 25 identical modules in one order eliminates the need to source boards individually and ensures consistent MP2307 performance across every prototype. Designers can populate multiple test rigs, equip a classroom bench or keep spares on hand without re-qualifying a different layout each time.

Questions about this item

How do I wire the Mini 360 module and adjust its output voltage?

Connect a DC source between 4.75 V and 23 V to the input pins, then turn the onboard potentiometer while measuring the output until it reads between 1.0 V and 17 V; the MP2307 IC regulates at 340 kHz.

What maintenance does the Mini 360 buck converter need over time?

No scheduled maintenance is required; if operated continuously at the 3 A limit, add a heatsink to the MP2307 IC so the 96 % peak efficiency is maintained and the inductor stays within thermal limits.

What is the first limitation reached when running the Mini 360 at full load for long periods?

Thermal rise on the MP2307 IC becomes the limiting factor; the supplier notes that a heatsink must be enhanced for sustained 3 A output, otherwise the module will throttle or shut down.
