Description
The VI Chip^® bus converter is a high efficiency (>94%) Sine
Amplitude Converter™ (SAC™) operating from a 360 to 400V_DC
primary bus to deliver an isolated, ratiometric output voltage from
11.3 to 12.5V_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 BCM384x120y300Azz is 1/32, the capacitance value
can be reduced by a factor of 1024x, resulting in savings of board
area, materials and total system cost.
The BCM384F120y300Azz 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 BCM384x120y300Azz increases overall
system efficiency and lowers operating costs compared to
conventional approaches.
