MI-RAM  
Military COTS Ripple Attenuator Modules  
Features  
Reduces output PARD to <10 mV pp  
Full attenuation up to 20 A load  
93%-99% efficiency  
Converter sense, trim, OV  
and OC retained  
Compatible with all MI-Series units  
from 5 to 50 Vdc output  
MIL-STD-810 environments  
No adjustments required  
Size: 2.28" x 2.4" x 0.5"  
(57,9 x 61,0 x 12,7 mm)  
Product Highlights  
The MI-RAM is designed for  
Specifications  
applications where extremely low  
noise outputs are required. When  
used with any Vicor MI-Series  
DC-DC converter, the MI-RAM  
reduces both line frequency related  
ripple and switching noise to less  
than 10 mV p-p, DC to 20 MHz.  
(At T = 25°C, unless otherwise specified)
