Product Description
The V•I Chip Bus Converter Module is a high efficiency
(>95%), narrow input range Sine Amplitude Converter
(SAC) operating from a 330 to 365 Vdc primary bus to
deliver an isolated low voltage secondary. The off-line
BCM provides an isolated 10.3 -11.4 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 V•I Chip package compatible with standard pick-and-
place and surface mount assembly processes. The
V•I 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.
