Description

The V•I Chip Bus Converter Module (BCM) B048K120T10 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 B048K120T10, 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 B048K120T10 achieves a power density of 400 W/in3 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 B048K120T10 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.
