Characterization of Power Hybrids for CMS Outer Tracker PS modules — •Alexander Bogner¹, Christian Dziwok², Lutz Feld¹, Katja Klein¹, Martin Lipinski¹, Alexander Pauls¹, Oliver Pooth², Nicolas Röwert¹, and Tim Ziemons² — ¹I.

For the Phase-2 Upgrade of the CMS Outer Tracker the CMS Collaboration is developing modules with two strip sensors (2S module) and modules with a strip and macro-pixel sensor (PS module). The upgrade will allow CMS to utilize the high luminosity provided by the future HL-LHC. The powering of an entire PS module will be driven by a so-called Power Hybrid (POH) featuring three DC-DC converters.
At RWTH Aachen University the POHs have been developed and were qualified regarding power stability, noise radiation and temperature profiles. In this talk the results and experience gained is presented.
