DESCRIPTION
The V•I Chip Bus Converter Module is a high efficiency (>95%)
Sine Amplitude Converter (SAC)^TM operating from a 360 to 400
Vdc primary bus to deliver an isolated 45 – 50 V nominal, un-
regulated secondary. The SAC offers a low AC impedance be-
yond the bandwidth of most downstream regulators, meaning
that input capacitance normally located at the input of a regula-
tor can be located at the input to the SAC. Since the K factor of
the VIB0002TFJ is 1/8, that capacitance value can be reduced by
a factor of 64x, resulting in savings of board area, materials and
total system cost.
The VIB0002TFJ is provided in a V•I Chip package compatible
with standard pick-and-place and surface mount assembly
processes. The V•I Chip package provides flexible thermal
management through its low junction-to-case and junction-to-
board thermal resistance. With high conversion efficiency the
VIB0002TFJ increases overall system efficiency and lowers
operating costs compared to conventional approaches.
