Features

RoHS compliant 50 W/in3 cULus, cT�Vus to 90% efficiency Size: x 12,7mm) Remote sense and current limit OVP, thermal shutdown Logic disable Wide range output adjust Compatible power booster modules ZCS power architecture Low noise FM control CE Marked Isolated output

Product Highlights The VI-200 family, with over 14 million units shipped, is Vicor's broad series of "zero-current-switching" component-level DC-DC converters. Operating at frequencies to 2 MHz, VI-200 family converters offer 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.

Note: For additional packaging options, please see page 4.

For additional output power, "booster" modules are available. (VI-Bxx-xx) Transient voltage for 1 second.
