End of Life BCM Bus Converter BCM48Bx030y210A00 S CUNRTL S C US Isolated Fixed Ratio DC-DC Converter Features & Benefits Product Ratings 48V 3V 210W Bus Converter V = 48V (38 55V) P = up to 210W DC DC IN OUT High efficiency (>94%) reduces system V = 3V (2.4 3.4V) OUT K = 1/16 (no load ) power consumption 3 High power density (>715W/in ) reduces Description power system footprint by >40% Contains built-in protection features: The VI Chip bus converter is a high efficiency (>94%) Sine Amplitude Converter (SAC) operating from a 38 to 55V n Undervoltage DC primary bus to deliver an isolated, ratiometric output voltage from n Overvoltage Lockout 2.4 to 3.4V . The Sine Amplitude Converter offers a low AC DC n Overcurrent Protection impedance beyond the bandwidth of most downstream regulators n Short circuit Protection therefore capacitance normally at the load can be located at the n Overtemperature Protection input to the Sine Amplitude Converter. Since the transformation ratio of the BCM48Bx030y210A00 is 1/16, the capacitance value Provides enable/disable control, internal can be reduced by a factor of 256x, resulting in savings of board temperature monitoring area, materials and total system cost. Can be paralleled to create multi-kW arrays The BCM48BF030y210A00 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 Typical Applications enhanced thermal management due to a large thermal interface area and superior thermal conductivity. The high conversion High End Computing Systems efficiency of the BCM48Bx030y210A00 increases overall system efficiency and lowers operating costs compared to Automated Test Equipment conventional approaches.
