ANDOVER, MA 01810 800-735-6200 vicorpower.com x 120 300A00 y B 48 BCM PRELIMINARY DATASHEET BCM™ Bus Converter SW1 enable / disable switch F1 V IN PC TM -Out +Out -In +In L O A D BCM TM Bus Converter FEATURES • 48 Vdc – 12 Vdc 300 W Bus Converter • High efficiency (>96%) reduces system power consumption • High power density (>1022 W/in3) reduces power system footprint by >40% • Contains built-in protection features: - Undervoltage - Overvoltage Lockout - Overcurrent Protection - Short circuit Protection - Overtemperature Protection • Provides enable/disable control, internal temperature monitoring • Can be paralleled to create multi-kW arrays TYPICAL APPLICATIONS • High End Computing Systems • Automated Test Equipment • High Density Power Supplies • Communications Systems DESCRIPTION The V•I Chip™ bus converter is a high efficiency (>96%) Sine Amplitude Converter™ (SAC™) operating from a 38 to 55 Vdc primary bus to deliver an isolated, unregulated 9.5 to 13.8 output. 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 BCM48BF120T300A00 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 BCM48BF120T300A00 is provided in a V•I Chip package compatible with standard pick-and-place and surface mount assembly processes. The co-molded V•I Chip package provides enhanced thermal management due to a large thermal interface area and superior thermal conductivity. The high conversion efficiency of the BCM48BF120T300A00 increases overall system efficiency and lowers operating costs compared to conventional approaches.
