Product Description
The V•I Chip Pre-Regulator Module 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•I 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 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
169 A/in3, or 195 W/in3 — 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.
