摘要

为了在大型强子对撞机(LHC)加速器升级粒子探测器中的应用,欧洲核子研究中心(CERN)开发了一种容辐射和磁场的10W负载点降压DC/DC变换器。DCDC基于FEAST2,这是一种在选定的商用高压CMOS技术中使用“按设计硬度”(HBD)技术设计的ASIC。介绍了该电路的主要特征,以及电特性以及TID、位移损伤(DD)和see的辐射数据。FEAST2满足大型强子对撞机实验的所有要求,也可能是空间应用的良好候选者。

FEAST2: A Radiation and Magnetic Field Tolerant Point-of-Load Buck DC/DC Converter
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.
