Vicor Corporation today announced the introduction of new, rugged, chassis-mountable versions of its DCM family of isolated, regulated DC-DC converters. These new converters provide all of the advantages of Vicor’s present DCM technology in a rugged new package (VIA packaging technology) that offers enhanced versatility in converter mounting and cooling. These “DCMs in a VIA package” are ideally suited for use in a broad range of industrial, process control, automotive, heavy equipment, communications and defense/aerospace applications.

The DCM family’s thermal and electrical performance is made possible by Vicor’s efficient, soft-switching ZVS conversion technology and Vicor’s thermally-adept Converter housed in Package (ChiP) packaging technology. Enclosing a ChiP converter in a rugged VIA package creates a mechanically robust product; simplifies mounting to a chassis or other external heat sinking device; and provides for improved thermal performance in a variety of applications.

Initially available DCM converters feature efficiencies up to 93% and include nominal 300 VDC input models (180 or 200 to 420 Vin range) at output voltages of 12, 24, and 48 V and at power levels up to 600 W, and nominal 28 VDC input models (16 to 50 Vin range) at output voltages of 12 and 24 V and at power levels up to 320 W (with other output voltages available soon). The new DCMs feature enhanced functional integration by incorporating EMI filtering, transient protection, inrush current limiting, and a secondary-referenced control interface for trim, enable and remote-sensing. Configurations are available for both on-board mounting and for chassis mounting.

Chassis mounting can offer system cost and performance advantages: moving the DC-DC conversion function off the board can reduce board size and cost, or it can free up valuable board real estate for other uses, and taking advantage of an existing chassis for heat removal can eliminate the need for, and cost of external heat sinks, while also providing improved thermal performance.

Chassis-mount DCM converters in VIA packaging are available from Vicor today; C and T-grades are generally available from Vicor authorized distributors. Future entries in this product family will include additional package sizes, input voltage ranges, power levels, along with PCB mounting and M-grade versions (-55°C operation, available in Q1 2016).
