It is specifically designed to provide PC to -In -0.3 to 6.0 Vdc a controlled Factorized Bus distribution voltage for PR to -In -0.3 to 9.0 Vdc TM powering downstream VTM Transformer fast, IL to -In -0.3 to 6.0 Vdc efficient, isolated low noise Point-of-Load (POL) TM VC to -In -0.3 to 18.0 Vdc converters. In combination, PRMs and VTMs form a +Out to -Out -0.3 to 59 Vdc complete DC-DC converter subsystem offering all of the unique benefits of Vicors Factorized Power SC to -Out -0.3 to 3.0 Vdc TM TM Architecture (FPA) : high density and efficiency low VH to -Out -0.3 to 9.5 Vdc noise operation architectural flexibility extremely fast OS to -Out -0.3 to 9.0 Vdc transient response and elimination of bulk capacitance CD to -Out -0.3 to 9.0 Vdc at the Point-of-Load (POL). SG to -Out 100 mA In FPA systems, the POL voltage is the product of the Continuous output current 2.5 Adc Factorized Bus voltage delivered by a PRM and the Continuous output power 120 WK-facto (the fixed voltage transformation ratio) of a MSL 4 downstream VTM. The PRM controls the Factorized Bus Case temperature during reflow 245 C (Datecode 1528 voltage to provide regulation at the POL. Because VTMs and later) perform true voltage division and current multiplication, Operating junction temperature -40 to 125 C T-Grade the Factorized Bus voltage may be set to a value that is substantially higher than the bus voltages typically Storage temperature -40 to 125 C T-Grade found inintermediate bu systems, reducing distribution losses and enabling use of narrower DC-DC Converter distribution bus traces. A PRM-VTM chip set can provide up to 100 A, or 115 W, at a FPA system density of 3 3 169 A/in , or 195 W/in and because the PRM can VC VH be located, orfactorized remotely from the POL, P C SC +Out Factorized SG +In 0.01 F TM IL OS these power densities can effectively be doubled.
