Vicor – New military-grade DC-DC converter modules offer very high power density


Vicor has released four new military-grade (MIL-COTS) versions of its VIA DCM family of compact, high-power DC-DC converter modules. The new modules support operation at extreme temperatures as low as -55°C.

The four new parts are in the 3414 VIA DCM family, operating from an input-voltage range of 16V to 50V DC. The parts have nominal output voltages of 5V, 12V, 24V or 28V, and provide output power of up to 320W.

Like other members of the VIA DCM family, the 3414 VIA DCM modules are rugged DC-DC converters in a thermally efficient VIA package which has a low 9.3mm profile. The modules are approximately 2.5 times more power-dense by volume and 3 times more power-dense by weight than the closest competitor’s products, as well as offering superior thermal performance.

The modules are also, like standard power bricks, very easy to implement in power-systems designs; unlike a power brick, they have a very slim and compact package
outline. This means that users of 28V VIA DCM modules can quickly develop extremely power- dense, low-profile, high-performance products.

Complementing the new MIL-COTS VIA DCMs is a new MFM 28V filter module, which provides front-end transient protection and EMI filtering when used with any Vicor military- grade 3414 VIA DCM module.

This combination enables power engineers to rapidly achieve conformance to:

• MIL-STD-461E/F for conducted emissions and conducted susceptibility
• MIL-STD-704A/E/F and MIL-STD-1275D/E for input transients

The MFM 28V filter module is housed in a 1714 VIA package measuring 44.6mm x 35.5mm x 9.3mm, accepts an input voltage of 16V to 50V DC, and can deliver up to 350W of power.
