The VIA DCM family from Vicor are ruggedised modular DC/DC converters in a thermally adept, 9.3mm VIA package, with wide input voltage range specifications and isolated, regulated high efficiency outputs.

The DC/DC converter family features EMI filtering, transient protection and inrush current limiting, as well as a secondary-referenced control interface for trim, enable and remote-sensing.

According to the company, the solutions are 2.5 times more power dense by volume and approximately three times more power dense by weight. Designers can expect better thermal performance and a more comprehensive range of transient and EMI spec compliance suitable for military application power design.

Four MIL-COTS (M-Grade) versions are now available, providing operation in temperatures down to -55°C in the 28V (16 to 50V DC) input voltage range with nominal output voltages of 5V, 12V, 24V and 28V and up to 320W of output power.

Complementing these VIA DCMs is a new MFM 28V filter module. This dense, low profile filter provides front-end transient protection and EMI filtering when used with any company M-Grade 28V 3414 VIA DCM module.

This combination is said to enable 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 filter is housed in a 1714 VIA package measuring 44.6 x 35.5 x 9.3mm, accepts an input voltage of 16 to 50V DC and can deliver up to 350W of power.
