MI-RAM General Description
The MI-RAM is designed for military 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 10mV p-p, DC to 20MHz.
The combination of the MI-RAM with an MI converter provides the output noise performance of a linear supply at a power density in excess of 15W/in3.
All of the features of the MI-Series 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.
All units are manufactured in ISO 9001-registered facilities. Full epoxy encapsulation in a low profile package enables the MI-RAM to meet MIL-STD-810 environmental testing requirements.
