Oral

A low voltage power supply provides the regulated output voltage of a few volts from the supply voltage around 48 V. The low voltage power supply incorporates a ceramic transformer which utilizes piezoelectric effect to convert voltage. The ceramic transformer isolates the secondary from the primary, thus providing the ground isolation between the supply and the output voltages. The ceramic...

58. High Radiation Resistant DC-DC Converter Regulators for use in Magnetic fields for LHC High Luminosity Silicon Tracker

Oral

We have found at least one commercial Buck regulator with integrated inductor fabricated with 0.25µm CMOS technology. This device was exposed to a Cobalt 60 source at BNL; there was negligible effect to 100 mega rad dosage (when the exposure was terminated). System implementation issues are being evaluated.

48. Inductor based switching DC-DC converter for low voltage power distribution in SLHC

Oral

In view of a power distribution scheme compatible with the requirements of future trackers in SLHC, we are evaluating the feasibility of on-board inductor based DC-DC step-down conversion. Such converter should be integrated and capable of operating in radiation environments and magnetic field. We present results concerning the choice of the CMOS technology for the integrated circuit, the...
