Product Overview
The VI BRICK 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
VI BRICK Current Multiplier Modules — fast,
efficient, isolated, low noise Point-of-Load
(POL) converters. In combination, VI BRICK
PRMs and VTMs^TM 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
VI BRICK 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 Military
COTS VI BRICK PRM-VTM chip set can provide
up to 100 A or 120 W at a FPA system power
density of 156 W/in³.
The Military COTS VI BRICK 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.
