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)

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 15 W/in3.
