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...

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.

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...
