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.
