Five new MIL-COTS parts optimise SWaP-C attributes


The VIA DCM family are ruggedised modular DC-DC converters in a thermally adept, low-profile (9.3 mm) VIA package, with wide input voltage range specifications and isolated, regulated high-efficiency outputs.

This new DC-DC converter family, features enhanced functionality and performance, including EMI filtering, transient protection, inrush current limiting, as well as a secondary-referenced control interface for trim, enable and remote-sensing.

Vicor’s new solutions are approximately 2.5X more power dense by volume and approximately 3X more power dense by weight than the closest competitor. Designers can expect better thermal performance and a more comprehensive range of transient and EMI spec compliance.

By providing brick-like modularity and ease-of-use  in a smaller form factor, the new VIA DCM and MFM modules enable system designers to develop extremely dense, low profile, high performance products fast.   The new solutions help you get to market faster by eliminating many of the uncertainties and compliance problems traditionally associated with military application power design.

New MIL-COTS Parts
Four new MIL-COTS (M-Grade) versions are available now, providing operation down to -55°C, in the 28V (16 – 50 VDC input voltage range) 3414 VIA DCM family with nominal output voltages of 5V, 12V, 24V and 28V and up to 320 Watts of output power.

Complementing these MIL-COTS VIA DCMs  is a new MFM 28V filter module (MFM filter) This extremely dense, low profile filter provides front-end transient protection and EMI filtering when used with any Vicor M-Grade 28V 3414 VIA DCM module. This combination enables power engineers to rapidly meet conducted emissions and conducted susceptibility requirements per MIL-STD-461E/F and input transients per MIL-STD-704A/E/F and MIL-STD-1275D/E. The MFM 28V filter module is housed in a 1714 VIA package (size: 1.76” x 1.40” x 0.36” / 44.6 mm x 35.5 mm x 9.3 mm), accepts an input voltage of 16 – 50 VDC and can deliver up to 350 Watts of power.
