It is specifically designed to provide a controlled Factorized Bus distribution voltage for powering downstream VI Chip Voltage Transformation Modules — fast, efficient, isolated, low noise Point-of-Load (POL) converters. In combination, PRMs and VTMsTM form a complete DC-DC converter subsystem offering all of the unique benefits of Vicor’s Factorized Power Architecture (FPA): high density and efficiency; low noise operation; architectural flexibility; extremely fast transient response; and elimination of bulk capacitance at the Point-of-Load (POL). In FPA systems, the POL voltage is the product of the Factorized Bus voltage delivered by the PRM and the "K-factor" (the fixed voltage transformation ratio) of a downstream VTM. The PRM controls the Factorized Bus voltage to provide regulation at the POL. Because VTMs perform true voltage division and current multiplication, the Factorized Bus voltage may be set to a value that is substantially higher t...
