The MI-RAM is designed for applications  
where extremely low noise outputs are  
required. When used with any Vicor  
MI-Family DC-DC converter, the MI-RAM  
reduces both line frequency related ripple and  
switching noise to less than or equal to 10  
mV p-p, DC to 20 MHz.

Electrical Considerations  
The combination of the MI-RAM with an  
MI-Family converter provides the output  
noise performance of a linear supply at a  
power density in excess of 15 W/in3.  
Transient Response and Dynamic Range: Full rated noise attenuation will be maintained at  
the MI-RAM output for step load changes up to 10% of the rated output current of the source  
converter, with the MI-RAM exhibiting an underdamped output excursion of less than 10 mV pp.  
Some degradation in noise attenuation during the transient response period following the step may be  
exhibited for larger load changes. Adding output capacitance to the MI-RAM will improve the  
rejection over a larger dynamic range.  
All of the features of the MI-Family converter  
remain available while using the MI-RAM,  
including output voltage trimming, OVP and  
OTP (MI-200 only), current limiting, remote  
sense, and output inhibit.  
Sense Connection: Sense-in and sense-out connections are provided on the MI-RAM. Sense-in  
connections must be connected to the corresponding sense connections on the Vicor converter.  
Sense-out pins on the MI-RAM must be connected between the MI-RAM power-output pins, and the  
point of load.  
Full encapsulation in a low profile package  
enables the MI-RAM to meet  
MIL-STD-810 environmental testing  
requirements.  
Output Load Characteristics: When used in combination with Vicor DC-DC converters, and  
with sense leads connected, the MI-RAM will be stable for any non-inductive load.  
DC Voltage Drop: Below full load, the input to output DC Voltage Drop is controlled to be an  
essentially constant voltage which appears between the –IN and –OUT terminals. In overload the DC  
voltage drop will rise as current increases. A few tens of millivolts appears between the +IN and  
+OUT terminals. Care should be taken not to connect IN and OUT terminals (i.e. through scope probe  
returns, grounds, etc.), as attenuation will be adversely affected.
