Product Description
The VI Chip Bus Converter Module
(BCM) is a high efficiency (>96%),
narrow input range Voltage
Transformation Module (VTM) operating
from a 48 Vdc bus to deliver an isolated
12 V secondary for Intermediate Bus
Architecture applications. The BCM may
be used to power non-isolated POL
converters or as an independent 12 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 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
800 W/in
3
and may be surface mounted
with a profile as low as 0.16" (4mm) over
the PCB. Its VI Chip power package is
compatible with on-board or in-board
surface mounting. The VI Chip package
provides flexible thermal management
through its low Junction-to-Case and
Junction-to-BGAthermal resistance.
Owing to its high conversion efficiency
and safe operating temperature range, the
BCM does not require a discrete heat sink
in typical applications. It is also
compatible with heat sink options,
assuring low junction temperatures and
long life in the harshest environments.
