Product Description

The V•I Chip Bus Converter Module

(BCM) is a high efficiency (>96%),

narrow input range Voltage

Transformation Module (VTM) operating

from a pre-regulated 48 Vdc primary 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.

Peak output current

The BCM achieves a power density of

400 W/in

and may be surface mounted

with a profile as low as 0.16" (4mm) over

the PCB. Its V•I Chip power BGA package

is compatible with on-board or in-board

surface mounting. The V•I 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

compatible with heat sink options,

assuring low junction temperatures and

long life in the harshest environments.

Notes

1. For complete product matrix see chart on page 10.

2. The referenced junction is defined as the semiconductor having the highest temperature. This

temperature is monitored by the temperature monitor (TM) signal and by a shutdown comparator.
