Exhibit 99.1
V-I Chip Delivers up to 80 Amperes at 0.9 to 1.8 Vdc;
Isolated POL Converter Sets New Records for
Speed, Density and Efficiency
ANDOVER, Mass.--(BUSINESS WIRE)--July 7, 2003--Vicor Corporation
(NASDAQ:VICR) today has introduced its first V-I Chip Voltage
Transformation Module (VTM), the V048K015T80. The VTM breaks records
for speed, density and efficiency to meet the demands of advanced DSP,
FPGA, ASIC, processor cores and microprocessor applications at the
point of load (POL) while providing isolation from input to output.
The VTM achieves a response time of less than 1 microsecond and
delivers up to 80 A in a volume of less than 0.25 cubic inch while
converting 48V to 1.5V with unprecedented efficiency. VTMs may be
paralleled to deliver hundreds of Amperes at an output voltage
settable from 1.0 to 1.8 Vdc, at no load, and 0.9 to 1.7 Vdc, at full
load.
The V-I Chip VTM is a key component of the Factorized Power
Architecture recently introduced by Vicor. Unlike the Intermediate Bus
Architecture, which feeds non-isolated POL converters or VRMs at
inefficiently low bus voltages, Factorized Power leverages a voltage,
designated Vf, controlled to minimize distribution losses while
allowing energy to be densely stored for sudden delivery to or
retrieval from the load by isolated VTMs. VTMs have 1 MHz bandwidth
and can provide efficient bi-directional power flow with the load,
limiting voltage excursions due to instantaneous load surges or dumps.
The open loop output resistance, Rout, of the V048K015T80 VTM is
approximately 1.3 milliohm and may be used to provide Automatic
Voltage Positioning for microprocessor loads. With its small SMD
footprint of only 1 square inch, the VTM obsoletes VRM sub-assemblies
and connectors, noted for their undesirable series impedance and heat
generation. The need for limited-life electrolytic or tantalum
capacitors at the POL characteristic of VRMs is also eliminated: the
VTM effectively multiplies capacitance present at its input to its
output with a gain in excess of 1,000 at up to 1 MHz. The net results
are higher performance and savings in material, board space and system
cost.
The VTM V048K015T80's output is 1.5 Vdc from a nominal 48 Vdc
input and is controllable at up to 80 A over the range of 0.9 to 1.8
Vdc with a Vf range of 32-57.6 Vdc. The VTM can be operated either
open- or closed-loop depending on the output regulation needs of the
application. Operating open-loop, the VTM output tracks its Vf input
voltage with a transformation ratio, K=1/32, and an output resistance,
Rout=1.3 milliohm, to enable applications requiring a programmable low
output voltage at high current and high efficiency. Closing the loop
back to an input Pre-Regulation Module (PRM) or DC-DC converter may be
used to compensate Rout.
The 1.5V VTM achieves break-through current density of 320 A/in3
in a V-I Chip package compatible with standard pick-and-place and
surface mount assembly processes. The V-I Chip BGA package supports
in-board mounting with a low profile of 0.16 inch (4mm) over the
board. A V-I Chip J-leaded package option will support on-board
surface mounting with a profile of 0.25 inch (6mm) over the board. The
V-I Chip outline dimensions are 1.26 x 0.85 x 0.24 inch (32 x 21.5 x 6
mm).
The V-I Chip BGA package provides flexible thermal management
through its low Junction-to-Case and Junction-to-BGA thermal
resistance. The V-I Chip J-lead package option will provide equivalent
thermal management performance with its Junction-to-Board thermal
resistance. The VTM's high efficiency, low thermal impedances and safe
operating temperature range eliminate the need for a heat sink in
typical applications. A 0.25 inch (6mm) pin fin heat sink option is
available for operation at maximum load in harsh thermal environments.
The VTM V048KT015T80 in the V-I Chip BGA package is priced as low
as 31 cents/A in OEM quantities and is available in JEDEC trays or
taped and reeled for automated pick and place and SMD assembly.
Delivery is 6 weeks ARO. Pre-assembled evaluation boards are available
for $49 and include the VTM.
