BCM Bus Converter BCM384x480y325Bzz S CUNRTL S C US Isolated Fixed Ratio DC-DC Converter Features & Benefits Product Ratings 384V 48V 325W Bus Converter V = 384V (360 400V) P = up to 325W DC DC IN OUT High efficiency (95%) reduces system V = 48V (45 50V) OUT K = 1/8 (no load ) power consumption 3 High power density (1106W/in ) reduces power system footprint by >40% Description Contains built-in protection features: The VI Chip bus converter is a high efficiency (95%) Sine n Undervoltage Amplitude Converter (SAC) operating from a 360 to 400V DC n Overvoltage Lockout primary bus to deliver an isolated, ratiometric output voltage from n Overcurrent Protection 45 to 50V . The Sine Amplitude Converter offers a low AC DC n Short circuit Protection impedance beyond the bandwidth of most downstream regulators n Overtemperature Protection therefore capacitance normally at the load can be located at the input to the Sine Amplitude Converter. Since the transformation Provides enable/disable control, ratio of the BCM384x480y325Bzz is 1/8, the capacitance value can internal temperature monitoring be reduced by a factor of 64x, resulting in savings of board area, materials and total system cost. Can be paralleled to create multi-kW arrays The BCM384F480y325Bzz 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 BCM384x480y325Bzz increases overall Automated Test Equipment system efficiency and lowers operating costs compared to conventional approaches.
