Optimizing DC-DC converter stability: AC and transient analysis in simulations of source impedance effects
Learn how to optimize DC-DC converter stability through AC analysis in the frequency-domain and transient analysis in the time-domain
MIL-COTS MI-RAM™ output filter
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 10mVP-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.
