Product Description
The PRM™ 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™ current multiplier — fast,
efficient, isolated, low noise Point-of-Load (POL)
converters. In combination, PRM modules and VTM
modules form a complete DC-DC converter subsystem
offering all of the unique benefits of Vicor’s Factorized
Power ArchitectureTM (FPATM) : 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 module
and the "K-factor" (the fixed voltage transformation
ratio) of a downstream VTM module. The PRM
regulator controls the Factorized Bus voltage to provide
regulation at the POL. Because VTM modules 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 PRM module-VTM
module 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 module can be located, or
"factorized," remotely from the POL, these power
densities can effectively be doubled.
The Military PRM module 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.
