Only $5 for 10 PCBs and Only $4.98 for 3D Printing + Express 24 hour service on http://www.pcbway.com/ Mini-360 is an ultra small and very cheap adjustable DC to DC step-down voltage regulator. It has been on the market for several years and there are several hardware version which rely on different switching voltage regulator chips from Monolithic Power Systems (MPS). The older models use MP2307DN. The newer models use MP1482DS. There is a potentiometer to adjust the output voltage. In this video we explored how to use Mini 360 to convert 12V DC power supply to 6V DC and to power an old JBL micro on stage speaker. Finally we tested the speaker on Lenovo ThinkPad Yoga with Thunderbold 4 docking station and Ubuntu Linux distribution.
