BCM Series BUS Converters

High efficiency narrow input range Sine Amplitude Converter from Vicor

Image of Vicor's BCM Series BUS ConvertersVicor's VI Chip bus converter is a high efficiency (>95%), narrow input range Sine Amplitude Converter (SAC™) operating from a 360 to 400 VDC primary bus to deliver an isolated low voltage secondary (ELV). The off-line BCM provides an isolated 11.3 -12.5 V distribution bus and is ideal for use in silver boxes and PFC front ends. Due to the fast response time and low noise of the BCM, the need for limited life aluminum electrolytic or tantalum capacitors at the input of POL converters is reduced—or eliminated—resulting in savings of board area, materials and total system cost.

The BCM achieves a power density of 1017 W/in³ in a VI Chip package compatible with standard pick-and-place and surface mount assembly processes. The VI Chip package provides flexible thermal management through its low junction-to-case and junction-to-board thermal resistance. Owing to its high conversion efficiency and safe operating temperature range, the BCM does not require a discrete heat sink in typical applications. Low junction-to-case and junction-to-lead thermal impedances assure low junction temperatures and long life in the harshest environments.
