Product Highlights
The MI-J00 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-J00
family offers exceptional performance in terms
of power density, efficiency, noise, ease of use,
and reliability.
The MI-J00 family meets the steady-state input
voltage requirements of MIL-STD-704D/E/F for
the 28V
DC
(MI-J2X) and 270V
DC
input (MI-J6X).
The 155V
DC
input (MI-J5X) meets MIL-STD-1399A.
When used with the MI-IAM input attenuator
module, the 28V or 270V input MI-J00 converter
meets the transient and spike requirements of
MIL-STD-704, MIL STD-1275, and DO-160. Please
refer to the MI-IAM data sheet for details.
The output voltage can be externally trimmed
or programmed from 50% to 110% of nominal
output. Current limiting, remote sense, and an
inhibit pin all combine to offer a high degree of
protection, versatility, and reliability for
power systems.
Fully encapsulated in Vicor’s industry standard
package, the MI-J00 family meets MIL-STD-810
environmental testing requirements for humidity,
fungus, salt-fog, explosive atmosphere,
acceleration, vibration, and shock.

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.
