MicroRAM™ Output Ripple Attenuator Module

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.
