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.

Output Connections and Considerations
The permissible load current
[e] must never be exceeded during
normal, abnormal or test conditions. Converters subject to
dynamic loading exceeding 25% of rated current must be
reviewed by Vicor Applications Engineering to ensure that the
converter will operate properly.
Under dynamic load, light load, or no load conditions, the
converter may emit audible noise. Converters that utilize remote
sense may require compensation circuitry to offset the phase
lag caused by the external output leads and load impedance.
Remote Sense leads must be protected for conditions such as
lead reversal, noise pickup, open circuit, or excessive output lead
resistance between the sense point and the converters output
terminals. For applications that may draw more than the rated
current, a fast acting electronic circuit breaker must be utilized
to protect the converter. Under no circumstance should the
rated current be exceeded. Utilizing or testing of current limit or
short circuit current will damage the converter. Ensure that the
total output capacitance connected to the converter does not
exceed the limits on Page 4.
Storage
Vicor products, when not installed in customer units, should
be stored in ESD safe packaging in accordance with
ANSI/ESD S20.20, “Protection of Electrical and Electronic
Parts, Assemblies and Equipment” and should be maintained
in a temperature controlled factory/warehouse environment
not exposed to outside elements controlled between the
temperature ranges of 15ºC and 38ºC. Humidity shall not be
condensing, no minimum humidity when stored in an ESD
compliant package.
