This power supply was heavily based off of KRALYN3D’s design.
His video is excellent so let’s go over the changes I made:
- A design refresh changing where things are and removing some extraneous inputs for my needs.
- Adding a AC input port (with a switch).
- Adding 45W USB-C charging
- Making fan 3 speed.
| Materials | Quantity | Cost |
| DC to DC Buck Converter LM2596 | 2 | $13 |
| DC Power Supply Control | 1 | $36 |
| USB C Output Module (45W) | 1 | $11 |
| Rocker Switch | 2 | $2 |
| XT60 Jack Female | 2 | – |
| Banana Plug | 1 | $6.70 |
| DC Jack | 2 | $.74 |
| 80x80x10 12V Fan | 1 | $10 |
| AC Input w/Switch | 1 | $12.3 |
| AC to DC 36V 5A DC 180W | 1 | $17 |
| Total | ~$110 |
Overall this was the largest soldering project I’ve ever undertaken, however this was key to my long term goals of portable tool sets. Between the power supply and soldering kit, I am able to solder and test electronics anywhere off of battery input.
