Product Summary

The VI-25L-IU, with over 12 million units shipped, is Vicor s broad series of “zero-current-switching” component-level DC-DC converters. Operating at frequencies up to 2 MHz, the VI-25L-IU converter offers exceptional power density, efficiency, noise performance, reliability and ease of use. Booster modules(VI-Bxx) provide a simple, cost-effective, off-the-shelf solution for higher power output requirements. One or more boosters may be used to create synchronous arrays capable of supplying several kilowatts of output power. The flexibility of Vicor s power components is also available in half-size, half-power VI-J00 MiniMods.
