MicroRAM™ Output Ripple Attenuator Module

DATA SHEET Select a Product

The MicroRAM output ripple attenuation module combines both active and passive filtering to achieve greater than 40dB of noise attenuation from 60Hz to 1MHz. The MicroRAM operates over a range of 3 – 30VDC, is available in either 20 or 30A models and is compatible with most manufacturers switching converters including the Vicor VI-200/VI-J00 and Maxi, Mini and Micro series DC-DC converters.

The MicroRAM's closed-loop architecture greatly improves load-transient response with dual-mode control and provides precise point-of-load voltage regulation. The MicroRAM supports redundant and parallel operation with its integrated ORing diode function.
