5 in 57,9 x 36,8 x 12,7 mm Product Highlights Vicor’s 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 to 30Vdc, is available in either 20 or 30A models and is compatible with most manufacturers switching converters including Vicor’s 1st and 2nd Generation 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 OR’ing diode function.
It is available in Vicor’s standard micro package (quarter brick) with a variety of terminations for through hole, socket or surface mount applications.
