Product Description
Absolute Maximum Ratings
The V•I Chip bus converter is a high efficiency (>95%),
narrow input range Sine Amplitude ConverterTM (SACTM)
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.
