BCM® Low Voltage Bus Converter Module Isolated, Fixed Ratio Bus Converter Family For use wherever 48V power architectures require small size, low weight, ® and extremely high power density. C S US C NRTL 6123 ChiP Description VI Chip Bus Converter Modules (BCMs) provide an isolated unregulated bus voltage to power Point-of-Load (PoL) converters. These BCMs provide a fixed ratio conversion to a broad range of output voltages. With peak efficiencies of up to 97.9% and power densities of up to 2,870 W/in3, VI Chip BCMs offer the most efficient and highest density, isolated power conversion available. Utilizing Vicor’s resonant Sine Amplitude Converter (SAC) topology, BCMs leverage high frequency Zero-Voltage Switching (ZVS) and Zero-Current Switching (ZCS) to deliver unmatched efficiency and power density with low noise and fast transient response. In addition, the BCM’s low AC impedance, beyond the bandwidth of most downstream regulators, enables bulk capacitance, normally located at the input of a regulator, to be placed at the high voltage input to the BCM. This reduces the bulk capacitance requirement and offers savings of board area and system cost. Offered in a range of packages, BCMs deliver a range of power, size and efficiency to exceed most customer needs.
