Ripple attenuator modules may be connected

to VI-200 or VI-J00 converters, FlatPACs,

ComPACs or MegaModules, with output

voltages from 5 – 50 V, to limit output noise

to less than 3 mV peak-to-peak at loads up

to 20 A. Combining active and passive

filtering, the VI-RAM attenuates both

low frequency input power source

fundamental and harmonics, as well as high

frequency switching components in the

frequency range of DC to 20 MHz, while

exhibiting efficiencies of 93-99%. No

adjustments are required, and remote sense

and output voltage trim features are retained.

A member of Vicor’s high-power density,

high performance, component-level

power building blocks, the VI-RAM offers

the power systems architect a single,

flexible, component-level solution to almost

any “clean power” problem. At the same

time, the VI-RAM eliminates the space,

efficiency, and weight penalties associated

with linear power sources, and the stability,

efficiency, and adjustment penalties

associated with external “add on” filters for

conventional switchers.

CE Marked

RoHS compliant (VE versions)

Reduces output ripple to < 3 mV pp

Compatible with any VI-200/VI-J00-

based product: 5 to 50 Vdc output

Full attenuation up to 20 A

No adjustments required

93 – 99% efficiency

Converter sense, trim, overvoltage

and overcurrent retained

the VI-RAM output for step load changes up to 10% of the rated output current of the source

converter, with the VI-RAM exhibiting an underdamped output excursion of less than 10 mV pp.

Some degradation in noise attenuation during the transient response period following the step may be

exhibited for larger load changes. Adding output capacitance to the VI-RAM will improve the

rejection over a larger dynamic range.

connections must be connected to the corresponding sense connections on the Vicor converter. Sense -Out

pins on the VI-RAM must be connected between the VI-RAM power-output pins and the point of load.

with sense leads connected, the VI-RAM will be stable for any non-inductive load.

essentially constant voltage which appears between the –IN and –OUT terminals. In overload the DC

voltage drop will rise as current increases. A few tens of millivolts appears between the +IN and

+OUT terminals. Care should be taken not to connect IN and OUT terminals (i.e. through scope probe

returns, grounds, etc.), as attenuation will be adversely affected.
