1.3V – 15.5V @ 2 Amps Power Supply

This is a small size power supply with low cost and easy to make that only taking about 5 more hours. I was very happy with it and would share with you.

Power Supply Specifications

Input: 5v-16v/3A DC

Output: 1.3V – 15.5V/2 Amps
Step 1: Materials and Tools

Here is a list of materials and tools I used for this project.


2 x LM2596S DC-DC module link

2 x Voltage/Current DC0-100V LED meter link

2 x WXD3-13-2W-10K link

2 x D3-13-2W knob link

2 x 4MM banana jacks(Red + Black) link

2 x 4MM banana sockets(Red + Black) link

1 x switch 117S 8.5*13.5MM link

1 x AMS1117-5V link

1 x 5V 30mm fan link

6 x 2.5mm/6mm screw

1 x DC adapter 16v / 3A, the voltage range between in 9v~16v would be better.

And take about 2 hours to print them.

I have removed the USB slot which the 2 holes on the front panel, the new one will not be any hole on it.
Step 3: Modify the DC-DC Converter
