Description
reduces power system footprint by >40%
• Contains built-in protection features:
n Undervoltage
The VI Chip® bus converter is a high efficiency (>95%) Sine
Amplitude Converter™ (SAC™) operating from a 38 to 55VDC
primary bus to deliver an isolated, ratiometric output voltage from
7.6 to 11.0VDC. 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 BCM48Bx096y240A00 is 1/5, the capacitance value
can be reduced by a factor of 25x, resulting in savings of board
area, materials and total system cost.
n Overvoltage Lockout
n Overcurrent Protection
n Short circuit Protection
n Overtemperature Protection
• Provides enable/disable control,
internal temperature monitoring
• Can be paralleled to create multi-kW arrays
The BCM48BF096y240A00 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 BCM48Bx096y240A00 increases overall
system efficiency and lowers operating costs compared to
conventional approaches.
