High B test of a commercial step-down Point of Load for LHC experiments

The performance in magnetic field (B-field) of the commercial DC-DC converter LTM8033, from Linear Technology, has been evaluated. The tests have been carried out at the Laboratorio Acceleratori e Superconduttività Applicata (LASA), in Milan (Italy), on December 2013 and the experimental results are here presented and discussed. Their ability to operate in hostile environment is particularly interesting for physics experiments where the presence of radiation and strong B field make electronic devices challenged to function. In particular, in this article the operation in high B-field environment will be investigated and discussed.
