Vicor Announces MIL-COTS 28 V DC-DC VoI Chip Modules



Andover, MA, May 3, 2007...Vicor Corporation (NASDAQ: VICR) announced the availability of MIL-COTS 28 V DC-DC VoI Chip modules. This new product line consists of a 28 Vdc input PRM(TM) regulator and a family of VTM(TM) current multipliers with output voltages from 1 to 50 Vdc. The PRM and VTM chipset provides the full functionality of a DC-DC converter with high efficiency and higher power density, fast transient response, low noise, and flexible thermal management. With each module weighing only 0.5 oz or 15 grams and measuring just 1.28 x 0.87 x 0.26 inches, the chipset offers specific advantages for designing power systems in mission-critical portable and airborne applications.

A PRM and VTM chipset can provide up to 100 A or 115 W for a system density of 172 A/in³ or 198 W/in³ and because the PRM can be located, or factorized, remotely from the point of load, these current and power densities can effectively be doubled at the load itself. The modules may be paralleled for higher power arrays. A compatible filter (M-FIAM7) is available that provides EMI filtering in compliance with MIL-STD-461 and transient suppression in compliance with MIL-STD-1275, MIL-STD-704 and DO-160.

The VoI Chip package is compatible with standard pick-and-place surface-mount machinery and assembly processes. It provides flexible thermal management through its low junction-to-case and junction-to-board thermal resistance.

"These new MIL-COTS products not only give power designers the full functionality of a DC-DC converter in a very small package, they provide breakthrough performance and flexibility in a rugged, highly efficient package," said Keith Nardone, Sr. Manager, Defense Products.

A MIL-COTS PRM and VTM chipset is available for less than $170 in OEM quantities. MIL-COTS VoI Chips are in mass production and are available immediately from stock. Evaluation Boards are available to evaluate the entire family of MIL-COTS 28 V DC-DC VoI Chip Modules. Each PRM and VTM is surface mounted to a unique PWB that can be mated using integral connectors. Evaluation boards are also available from stock and priced at $219.00 each. To order, contact Vicor Customer Service at 800-735-6200 or e-mail custserv@vicr.com.
