Vicor VI-RAM™ Ripple Attenuator Modules reduce output ripple to less than 3mV peak-to-peak at loads up to 20A, and are compatible with VI-200/VI-J00 series products, with output voltages from 5 to 50V. They exhibit 93-99% efficiency, and retain remote sense and output voltage trim features.
The VI‑RAM ripple attenuator modules are designed to connect to Vicor VI‑200 or VI‑J00 converters, providing output voltages from 5 VDC to 50 VDC and handling loads up to 20 A. They combine active and passive filtering to achieve output ripple below 3 mV pp with efficiencies of 93‑99% and require no adjustments.
Key features include 500 V RMS isolation, compact size (2.28" × 2.4" × 0.5"), and retained sense, trim, over‑voltage and over‑current protection. The datasheet details electrical characteristics, transient response, and mechanical dimensions.
