The upgrade of the ATLAS TileCal LVPS falls under the HL-LHC upgrade. This upgrade is composed of multiple projects that when combined will form the latest iteration of the LVPS. One such project is focused on an LVPS component known as a brick. These bricks function to step-down bulk 200V DC current to the 10V DC current required by the front-end electronics of a TileCal module and are exposed to high levels of radiation as well as a strong magnetic ﬁeld due to the operating environment within the ATLAS detector. This resulted in bricks being of highly refined custom design.
