Abstract
The Minimum Ionizing Particle Timing Detector (MTD) will be introduced in the Compact Muon Solenoid (CMS) experiment to measure the production time of Minimum Ionizing Particles (MIPs). Power Conversion Cards (PCCs) regulates and supplies low voltage to front end electronics of the MTD barrel, the Barrel Timing Layer (BTL). The PCCs host three radiation and magnetic field tolerant DC-DC converters. The physical height of the PCC is limited to 7 mm, having necessitated development of custom inductors and shields. Additionally, the CMS Electromagnetic Calorimeter will be upgraded. On-detector Low Voltage Regulator (LVR) cards host four DC-DC converters and one linear regulator. In these proceedings we will present both cards’ designs evolution, stack-up and layout optimization, noise filtering choices and a performance evaluation.
