Vicor offers five new MIL-COTS parts to simplify designs and optimize SWaP-C 

Ruggedised, modular DC/DC converters from Vicor, the VIA DCM family, are offered in a thermally adept, low profile (9.3mm) VIA package. Designers can expect better thermal performance and a more comprehensive range of transient and electromagnetic interference (EMI) spec compliance, says Vicor. 

The DC/DC converters in the VIA DCM family have wide input voltage range specifications and isolated, regulated high efficiency outputs. The family members feature 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.

The models added by Vicor are claimed to be approximately x2.5 more power dense by volume and approximately x3 more power dense by weight than the closest competitor.

By providing brick-like modularity and ease-of-use in a smaller form factor, the VIA DCM modules, and MFM filter module, enable system designers to develop extremely dense, low profile, high performance products quickly. The converters also speed time to market by eliminating many of the uncertainties and compliance problems traditionally associated with military application power design, reassures Vicor.

The latest additions are four MIL-COTS (M-Grade) versions. They operate down to -55 degree C, in the 28V (16 to 50 V DC input voltage range) The 3414 VIA DCM family has nominal output voltages of 5.0, 12, 24 and 28V and up to 320W of output power.

Complementing these MIL-COTS VIA DCMs  is a new MFM 28V filter module. 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. According to Vicor, 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, measuring 1.76 x 1.40 x 0.36-inch (44.6 x 35.5 x 9.3mm). The MFM filter accepts an input voltage of 16 to 50 V DC and can deliver up to 350W of power.
