Universally compatible ripple attenuation module

21 May 2003 Power Electronics / Power Management

The MicroRAM Output Ripple Attenuation Module from Vicor combines both active and passive filtering to provide >40 dB conducted differential noise attenuation from 60 Hz to 1 MHz. This makes it ideal for applications that demand low noise and stable DC voltage levels, even under severe transient load conditions.

The MicroRAM, in Vicor's standard micro package (quarter brick), is available in 20 A and 30 A versions and can be used with most DC output power supplies providing from 3-30 V d.c. to the load. The MicroRAM's closed-loop architecture greatly 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 capabilities. 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.
