DCDCv9-3
About the DCDCv9-3 PCB
DCDCv9-3 is an open source PCB design by Rootthecause, published on GitHub under the CERN-OHL-W-2.0 license. It is a 4-layer board measuring 85.6 × 54 mm, with 186 components from 83 distinct parts.
Other key parts include the RP-1212S, RT9058-90GVL, MP4541GN-Z, TLV61048DBVR and NCP4305DMTTWG. By type, the board carries 71 resistors, 52 capacitors, 18 diodes, 14 ICs, 11 transistors and 8 connectors.
From the project
An open source credit card sized DC/DC converter to convert up to 600 V to 24 V in a energy-, cost- and space efficient way.
I've designed a High Voltage DC/DC Converter to replace our LV Battery. Feel free to use it as well! Although this design (and previous versions) have passed two times FSG scrutineering and have been operating without any issues for over 6 months, always manufacture at your own risk! If you encountered any bugs or have suggestions for improvement, please use the GitHub issues form. For discussions and technical questions, kindly use the discussion bord.
