Vicor announces the availability of MIL-COTS 28 V DC-DC V•I Chip modules. This new product line consists of a 28 Vdc input PRM™ regulator and a family of VTM™ 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 15 grams and measuring just 32.5 x 22 x 6.6 mm, 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 V•I 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.

A MIL-COTS PRM and VTM chipset is available for less than $170 in OEM quantities (FOB Andover). MIL-COTS V•I 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 V•I 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 (FOB Andover).
