Description
I needed a compact protective case for the common LM2596/LM2596S Dual-USB buck converter (5 V/3 A).
The enclosure is intentionally simple and needs no screws or additional hardware.
Board specs
- Input: 6 to 40 V DC (typical use at 9 V / 12 V / 24 V / 36 V) via 5.5 x 2.1 mm barrel jack or 2-pin screw terminal
- Output: 2x USB A
- Board size: about 50 x 35 x 12 mm
- Keywords for board: LM2596 Dual USB Step Down
Dimensions
- Enclosure: 41 x 53 x 22 mm
- Lid: 51 x 53 x 5 mm
Assembly
- Align the PCB with the three internal locator pins (USB ports facing the openings) and press down evenly until it snaps/seats into place. Avoid pressing on the trimpot, apply light pressure near the board edges.
Printing
- PETG and PLA are both working good and tested.
