VI Chip® BCM® Bus Converter Family Description ® C VI Chip Bus Converter Modules (BCMs) provide an isolated unregulated bus voltage to power Point-of-Load (PoL) converters. The BCMs provide a fixed ratio conversion from either a high input voltage (ranging from 230 – 410 V depending on the model) or a 48 V (38 – 55 V) input voltage to a broad range of output bus voltages. With peak efficiencies of up to 97.9% and power densities of up to 1,880 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 VI Chip full and half-sized packages, as well as the new 6123 ChiP package, BCMs deliver a range of power, size and efficiency to exceed most customer needs.
