DC-DC Converter Array Stays Cool With Vertical-Mount Heatsink

The VI BRICK BCM Array DC-DC converter modules enable high-power bus conversion and facilitate thermal management in a reduced board space by means of an integrated vertical mount heat sink. This high-efficiency (typically 95 percent), high-power (up to 650 W), vertically-mounted BCM array provides isolation and conversion from 380 V to 12 or 48 V for low-voltage distribution near the point of load. VI BRICK BCM Arrays include high voltage bus converters that are ideal for PFC front-end applications providing the capability of a high voltage bus with minimal distribution loss. They are available with 384 and 352 nominal input voltages and output voltages of 11, 12, 44, and 48 Vdc. The efficiency and compact size of these modules yields fast transient response and power density up to 290 W/in.³. These models will be available with output power up to 650 W in a board space of less than two square inches in a one-unit-high package. The vertical package orientation also provides better exposure of the heatsink to system airflow. The 384-V input modules are available from stock in sample-size quantities. Standard lead time for higher quantities is four to six weeks. Pricing for the VI BRICK BCM Array family is as low as $109 in OEM quantities. VICOR CORP., Andover, MA. (800) 735-6200.
