Product Overview

The VI BRICK Pre-Regulator Module is a very efficient non-isolated regulator specifically

designed to provide a controlled Factorized Bus distribution voltage for powering

downstream VI BRICK Voltage Transformation Modules. In combination, VI BRICK PRMs

and VTMs

benefits of Vicor’s Factorized Power Architecture (FPA): high density and efficiency; low

noise operation; architectural flexibility; extremely fast transient response; elimination of

bulk capacitance at the Point-of-Load (POL); in a thermally enhanced package.
