KC_NixieSupply5vto160v: Kicad schematic, PCB layout, BOM. The footprint is 1.5" x 1.5" and was described and optimized in Part 2 of the blog. The Board can be ordered from from OSH Park

KC_NixieSupply5vto170vMini: KiCad schematic, PCB Layout, BOM of the "mini" version of the supply. This has a footprint of 1.5" x 1" by using smaller output capacitors and using the KiCad power tools to shrink the layout. This is the system defined by part 3 of the blog. The layout has all the same constraints as in Part 2. It still has four mounting holes, a USB input connector and a Terminal output connector. You can order the board from Order from OSH Park

SimCalcFiles: Spice simulation files and DCM Efficiency Calculations. NOTE: The LTSPICE (TM) simulation has trouble finding an initial operating point. To get the simulation to start, use the ESC key and press it twice to skip the initial operating point. This allows the simulation to continue and will provide a good transient response.

Datasheeets: Datasheets for different inductors and the power fet. In the Kicad Schematic, the part numbers and Digikey (TM) links are listed already. Also the complete BOM is located in the KICAD Directory.
