The Brick Business Unit of Vicor has announced the introduction of the VI Brick BCM Array. This is a high-efficiency (typically 95%), high power (up to 650W), vertically mounted BCM array, that provides isolation and conversion from 380V to 12 or 48V for low voltage distribution near the Point-of-Load (POL). It incorporates the superior technical attributes of V•I Chip technology in a robust package that facilitates thermal management.

It incorporates the superior technical attributes of V•I Chip technology in a robust package that facilitates thermal management.

The combination of a high voltage bus converter with an integrated heatsink that simplifies thermal management and minimises board space is unique and has already been adopted by major customers. The VI Brick BCM Array is ideal for PFC front-end applications, providing the capability of a high voltage bus with minimal distribution losses. This is a highly efficient solution for applications using POL and is available with 384V and 352V nominal input voltages, and output voltages of 11, 12, 44 and 48VDC. The efficiency and compact size of these modules yields power density up to 290W/in3 and fast transient response. Models with output power up to 650W in a board space of less than 2in2 will also be available, in a 1U high package. The vertical package orientation also provides better exposure of the heatsink to system airflow.

The new VI Brick BCM Arrays are ideally suited for server applications using a PFC front-end requiring relatively high power levels with challenging thermal issues. The offline power can be bussed to the motherboard and converted to either 48V or 12V, which minimises distribution losses, reduces conversion steps, improves efficiency and reduces overall cost. In addition, less capacitance required for energy storage near the load returns further space and cost savings.

These products can be used in a wide variety of applications that require high efficiency, high power density, improved thermal management, low noise, fast transient response and overall design flexibility. The 384V input modules are immediately available from stock in sample size quantities. Standard lead time for higher quantities is four to six weeks.
