BCM

Bus Converter

• 384 V to 12 V V•I Chip

• 300 Watt (450 Watt for 1 ms)

• High density – up to 1017 W/in

• Small footprint – 260 W/in

• Low weight – 0.5 oz (15 g)

• ZVS / ZCS isolated sine

Product Description

The V•I Chip bus converter is a high efficiency (>95%),

narrow input range Sine Amplitude Converter

operating from a 360 to 400 Vdc primary bus to deliver

an isolated low voltage secondary (ELV).

The off-line BCM provides an isolated 11.3 -12.5 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/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.
