Description
The VI Chip^® bus converter is a high efficiency (95%) Sine
Amplitude Converter™ (SAC™) operating from a 360 to 400V_DC
primary bus to deliver an isolated, ratiometric output voltage from
45 to 50V_DC. The Sine Amplitude Converter offers a low AC
impedance beyond the bandwidth of most downstream regulators;
therefore capacitance normally at the load can be located at the
input to the Sine Amplitude Converter. Since the transformation
ratio of the BCM384x480y325Bzz is 1/8, the capacitance value can
be reduced by a factor of 64x, resulting in savings of board area,
materials and total system cost.
The BCM384F480y325Bzz is provided in a VI Chip package
compatible with standard pick-and-place and surface mount
assembly processes. The co-molded VI Chip package provides
enhanced thermal management due to a large thermal interface
area and superior thermal conductivity. The high conversion
efficiency of the BCM384x480y325Bzz increases overall
system efficiency and lowers operating costs compared to
conventional approaches.
