What it is
A 500W Variable PSU with real time CC/CV error correction, current clamping, a 16 bit DAC for millivolt and milliamp precision.
Why I Made This
Precision power supplies are really cool, and high power power supplies are also really cool, some precision PSUs having milliamp/millivolt precision, and some high power PSUs going upto 2kW, but I couldn't find a single power supply with more than 300W with sub volt precision for under a lot of money, and I've always wanted to design one since they're really impressive, so I did.

Questions
How big is the DufocklianPower PCB?
It measures 80 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DufocklianPower use?
85 parts, built around the ESP32-S3-WROOM-1-N8, DAC8562EP, LM5164DDA and AP2112K-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the DufocklianPower KiCad files?
From the asadpetwalker/benchpowersupply repository on GitHub, at the commit this page was made from: the board is DufocklianPower/DufocklianPower.kicad_pcb and its schematic DufocklianPower/DufocklianPower.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DufocklianPower design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
