Description
The VI Chip^® bus converter is a high efficiency (>96%) Sine
Amplitude Converter™ (SAC™) operating from a 38 to 55V_DC
primary bus to deliver an isolated, ratiometric output voltage from
9.5 to 13.8V_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 BCM48Bx120y300A00 is 1/4, the capacitance value can
be reduced by a factor of 16x, resulting in savings of board area,
materials and total system cost.
The BCM48BF120y300A00 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 BCM48Bx120y300A00 increases overall
system efficiency and lowers operating costs compared to
conventional approaches.
