The new Vicor DCM2322 family of isolated DC-DC converters targets lower-power rail EN50155 infrastructure applications

Modern rail infrastructure requires a wide range of DC-DC converters to power a variety of new safety systems and passenger services, as well as creating a need for performance improvements in existing systems for both freight and commuter markets. Power density, efficiency and ease of use are critical considerations when designing isolated, regulated DC-DC converter systems for modern rail applications. The new DCM2322 ChiP family is a lower-power and smaller package variant of the DCM3623 family and provides power system engineers a smaller footprint option with input voltage ranges that meet multiple EN50155 standards.

Packaged in a 22 x 23 x 7mm ChiP, the new series offers engineers wide input voltage ranges of 43 – 154V and two more narrow input voltage ranges of 14 – 72V and 9 – 50V, with power levels ranging from 35 to 120W and efficiencies up to 90.5%.

The extensive family of isolated DCMs utilize the Vicor high-frequency zero-voltage switching topology to achieve industry-leading thermal and electrical performance, with power densities five times greater than competing DC-DC converters.

In additional to modern rail applications the DCM2322 is excellent for powering a broad range of robotics, UAV, communications and defense/aerospace applications.
