Note:
(1) The referenced junction is defined as the semiconductor having the highest temperature.
This temperature is monitored by a shutdown comparator.
K indicates BGA configuration. For other
mounting options see Part Numbering below.
Product Description
The VI Chip Bus Converter Module (BCM) is a high
efficiency (>94%), narrow input range Sine Amplitude
Converter (SAC) operating from a 38 to 55 Vdc primary
bus to deliver an isolated 2.38 V to 3.43 V secondary.
The BCM may be used to power non-isolated POL
converters or as an independent 2.38 – 3.43 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 current density of 284 A/in
3
and
may be surface mounted with a profile as low as 0.16"
(4 mm) over the PCB. Its VI Chip power package is
compatible with onboard or inboard surface mounting.
The VI Chip package provides flexible thermal
management through its low Junction-to-Case and
Junction-to-BGA 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. It is also available with heat sink
options, assuring low junction temperatures and long
life in the harshest environments.
