VI BRICK BCM modules use advanced Sine
Amplitude Converter
TM
(SAC
TM
) technology,
thermally enhanced packaging technologies,
and advanced manufacturing processes to
provide high power density and efficiency,
superior transient response, and improved
thermal management. These modules can be
used to provide an isolated intermediate bus to
power non-isolated POL converters and due to
the fast response time and low noise of the
BCM, capacitance can be reduced or
eliminated near the load.
