Vicor Intros MicroRAM Ripple Attenuation Module

Vicor Corp. (Andover, MA) announced its new MicroRAM output ripple attenuation module, which combines both active and passive filtering in Vicor's standard quarter-brick micropackage to provide >40dB conducted differential noise attenuation from 60Hz to 1MHz. The MicroRAM is rated for 20A and can be used with any dc-output power supply having an output voltage from 3Vdc to 30Vdc.

The MicroRAM's closed-loop architecture improves the load-transient response of the power supply with precise point-of-load voltage regulation. The module can be configured for regulation control either by using the source's remote sense or voltage trim. The MicroRAM supports N+1 redundant and parallel operation with its integrated OR'ing diode function. It is available with a variety of terminations and mounting styles for through-hole, socket or surface-mount applications.

The new MicroRAMs are priced at $37 in OEM quantities and are available from stock.
