DESCRIPTION
The VI Chip Bus Converter Module is a high efficiency (>95%)
Sine Amplitude Converter (SAC)TM operating from a 330 to 365
Vdc primary bus to deliver an isolated 41.25 – 45.63 V nominal,
unregulated secondary. The SAC offers a low AC impedance
beyond the bandwidth of most downstream regulators, mean-
ing that input capacitance normally located at the input of a
regulator can be located at the input to the SAC. Since the K
factor of the VIB0003TFJ 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 VIB0003TFJ is provided in a VI Chip package compatible
with standard pick-and-place and surface mount assembly
processes. The VI Chip package provides flexible thermal
management through its low junction-to-case and junction-to-
board thermal resistance. With high conversion efficiency the
VIB0003TFJ increases overall system efficiency and lowers
operating costs compared to conventional approaches.
