About the Power supply lt3571 PCB

Power supply lt3571 is an open source PCB design by burbschat, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 75 × 50 mm, with 88 components from 20 distinct parts.

Other key parts include the MCP4728, LT357 and NUCLEO-F042K6. By type, the board carries 43 resistors, 25 capacitors, 5 ICs, 5 connectors, 4 inductors and 1 module.

It belongs with the power & battery and sensors designs in this gallery.

From the project

Simple SiPM/plastic scintillator based beam loss monitors

The sensors later have been re-purposed to detect beam loss and trigger a beam abort if there is too much of it. This application does not require very precise sensors. Further, opposed to the original design, now a larger dynamic range was desirable. To also allow for measurement of beam losses which occur for longer than a few microseconds, DC coupled analog electronics are required. The design published here was created to implement the required changes outlined above and create a system better suited to the current application at the SuperKEKB collider.
