The VI Chip ? regulator is a very efficient non-isolated
regulator capable of both boosting and bucking a wide
range input voltage. It is specifically designed to provide
a controlled Factorized Bus distribution voltage for
powering downstream VTM ? Transformer — fast,
efficient, isolated, low noise Point-of-Load (POL)
converters. In combination, PRMs and VTMs form a
complete DC-DC converter subsystem offering all of the
unique benefits of Vicor’s Factorized Power
Architecture TM (FPA) TM : 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 than the bus voltages typically

found in "intermediate bus" systems, reducing
distribution losses and enabling use of narrower
distribution bus traces. A PRM-VTM chip set can provide
up to 100 A, or 115 W at a FPA system density of
DC-DC Converter
169 A/in 3 , or 195 W/in 3 — and because the PRM can
be located, or "factorized," remotely from the POL,
these power densities can be effectively doubled.
