Abstract

In view of application in upgraded particles detectors at the LHC accelerator, CERN has developed a radiation and magnetic field tolerant 10W Point-Of-Load (POL) buck DC/DC converter. The DCDC is based on FEAST2, an ASIC designed using ´Hardness-By- Design´ (HBD) techniques in a selected commercial high voltage CMOS technology. The main features of the circuit, together with electrical characterization as well as radiation data for TID, Displacement Damage (DD) and SEEs are presented. FEAST2 meets all the requirements of the LHC experiments and is also a possible good candidate for applications in Space.
