A family of fully integrated (including all capacitors and inductors) rad-hard DCDC converters has been developed for the first time in the HEP community. This work presents the experimental results of three functional ASICs prototypes designed in a 28nm CMOS technology using 0.9V-rated transistors. All prototypes have been designed to withstand 1Grad. iPOL5V and iPOL2V3 are state-of-the-art...
Efforts aiming at consolidating the powering for the CMS detector have led to the development of a Low Voltage Power Supply (LVPS). The LVPS converts 380 VDC to 12 VDC, suitable for powering the widely used bPOL12V Point-Of-Load DC-DC converter. To limit cables size, the LVPS must be hosted in the CMS experimental cavern, being exposed to ionizing radiation and stray magnetic field of up to...
DC/DC converters that are tolerant to high magnetic fields and radiation are needed to improve the power distribution scheme of High Energy Physics (HEP) experiments. This paper presents 2 topics: firstly, an optimised rad-hard production-ready module for 48V to 5V-12V conversion (including) a custom PCB air core inductor, and secondly the outcome of a R&D program for developing next...
