Product Description
The V鈥 Chip Pre-Regulator Module (PRM) 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
V鈥 Chip Voltage Transformation Modules (VTMs) 鈥?/div>
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鈥檚 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 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 200 A/in
3
, or 230 W/in
3
鈥?and because the PRM
can be located, or "factorized," remotely from the
POL, these power densities can be effectively doubled.
The PRM described in this data sheet features a unique
"Adaptive Loop" compensation feedback: a single wire
alternative to traditional remote sensing and feedback
loops that enables precise control of an isolated POL
voltage without the need for either a direct connection
to the load or for noise sensitive, bandwidth limiting,
isolation devices in the feedback path.
