The future of standardized defense platforms using MOSA, SOSA and VPX open architectures
MIL-COTS 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 Vicor's MI-200/MI-J00 and Maxi, Mini and Micro series DC-DC converters.
The MicroRAM's closed-loop architecture greatly improves load transient response and with dual mode control, insures precise point-of-load voltage regulation. The MicroRAM supports redundant and parallel operation with its integrated ORing diode function.
