MI-RAM

Rugged output ripple attenuator for VI-200/VI-J00

The MI-RAM is designed for 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-series 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 logic enable/disable.
