BCM Bus Converter BCM352x110y300B00 S CUNRTL S C US Isolated Fixed Ratio DC-DC Converter Features & Benefits Product Ratings 352V 11V 300W Bus Converter V = 352V (330 365V) P = up to 300W DC DC IN OUT High efficiency (>95%) reduces system V = 11V (10.3 11.4V) OUT K = 1/32 (no load ) power consumption 3 High power density (>1022W/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 352 to 365V DC n Overvoltage Lockout primary bus to deliver an isolated, ratiometric output voltage from n Overcurrent Protection 10.3 to 11.4V . 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 BCM352x110y300B00 is 1/32, the capacitance value internal temperature monitoring can be reduced by a factor of 1024x, resulting in savings of board area, materials and total system cost. Can be paralleled to create multi-kW arrays The BCM352F110y300B00 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 BCM352x110y300B00 increases overall Automated Test Equipment system efficiency and lowers operating costs compared to conventional approaches.
