Product Description
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
VTMTM Transformer — 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
ArchitectureTM (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 230 W at a FPA system
density of 169 A/in3 or 390 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.
