Product Highlights
The MI-200 family of DC-DC converters is
designed for applications utilizing distributed
power architectures. Based on Vicor’s
VI-200 / VI-J00 family of zero-current
switching, component level DC-DC converters,
the MI-200 family offers exceptional
performance in terms of power density,
efficiency, noise, ease of use, and reliability.
Fully encapsulated in Vicor’s industry standard
package, the MI-Series meets MIL-STD-810
environmental requirements for humidity,
fungus, salt-fog, explosive atmosphere,
acceleration, vibration and shock.
Standard features, such as wide output
trimming/programming, current limiting,
remote sense, output inhibit, and latching
OVP and OTP combine to offer the highest
degree of protection, versatility, and reliability
for power systems.
