Product Description
The V•I Chip Bus Converter Module is a high efficiency
(>96%), narrow input range Sine Amplitude Converter
(SAC) operating from a 38.0 to 55 Vdc primary bus to
deliver an isolated 38.0 V to 55.0 V secondary. The BCM
may be used to power non-isolated POL converters or as
an independent 38.0 – 55.0 V source. Due to the fast
response time and low noise of the BCM, the need for
limited life aluminum electrolytic or tantalum capacitors
at the load 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
V•I Chip package compatible with standard pick-and-
place and surface mount assembly process. The V•I Chip
package provides flexible thermal management through
its low junction-to-board and junction-to-case 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.
