BCM® High Voltage Bus Converter Module Isolated, Fixed Ratio Bus Converter Family For use in high end computing systems, industrial systems, Telcom/datacom systems, ® C and 384 V DC power distribution architectures. S US C NRTL 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 from a high input voltage to common bus voltages used in intermediate bus architectures or as inputs to PoL devices. With peak efficiencies of up to 97.9% and power densities of up to 2,750 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 ZeroCurrent 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. 6123 ChiP Full VI Chip Overview n High power density: Up to 2,750 W/in3 in a 2.2 in2 footprint n Output power 6123: Up to 1.75 kW; Full: Up to 325 W n High Efficiency 6123: 97.9%; Full: 96% n Isolation Up to 4242 Vdc n Fast response time n Low noise n Protection Features: Undervoltage and overvoltage lockout, overcurrent protection, short circuit protection, over temperature protection n Bi-Directional n Simple analog or full featured PMBus control interface Input Voltage (V) Output Voltage (V) Output Power (W) Output Current (A) Package Type Control Interface BCM400P500x1K8A30 260 – 410 32.5 – 51.3 1,750 35.0 6123 ChiP Analog** BCM400P500x1K8A31 260 – 410 32.5 – 51.3 1,750 35.0 6123 ChiP PMBus* BCM384P120x1K5AC0 260 – 410 8.1 – 12.8 1,500 125 6123 ChiP Analog** BCM384P120x1K5AC1 260 –410 8.1 – 12.8 1,500 125 6123 ChiP PMBus* BCM380P475x1K2A30 260 – 410 32.5 – 51.3 1,200 25.7 6123 ChiP Analog** BCM380P475x1K2A31 260 – 410 32.5 – 51.3 1,200 25.7 6123 ChiP PMBus* BCM384P120x800AC0 260 – 410 8.1 – 12.8 800 68 6123 ChiP Analog** BCM384P120x800AC1 260 – 410 8.1 – 12.8 800 68 6123 ChiP PMBus* BCM380P475x800A30 260 – 410 32.5 – 51.3 800 16 6123 ChiP Analog** BCM380P475x800A31 260 – 410 32.5 – 51.3 800 17.2 6123 ChiP PMBus* BCM384x120T300A00 360 – 400 11.3 – 12.5 300 27.7 Full Analog BCM352x125x300A00 330 – 365 11.79 – 13.04 300 26.0 Full Analog BCM352x110T300B00 330 – 365 10.3 – 11.4 300 28.0 Full Analog BCM352x440T330A00 330 – 365 41.25 – 45.63 325 7.7 Full Analog BCM384x480T325A00 360 – 400 45.0 – 50.0 325 7.0 Full Analog MBCM270x338M235A00 240 – 330 30.0 – 40.25 235 7.3 Full Analog MBCM270x450M270A00 230 – 330 38.3 – 55.0 270 6.25 Full Analog Model Number *Require the use of D44TL1A0 digital supervisor and I13TL1A0 digital isolator ** Bi-Directional version also available.
