Description

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

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.
