48/12 V power converter in surface mount BGA package

4 June 2003 Power Electronics / Power Management

Vicor has introduced the first products based on its V-I Chip ball grid array (BGA) surface mount power component. The family consists of 48 V to 12 V Bus Converter Modules (BCM) for conventional Intermediate Bus Architecture (IBA) applications.

The 200 W B048K120T20 requires 21,5 x 32 mm of board space, which according to the supplier is less than a third the board area of intermediate bus converters in quarter brick style packages.

Available in two mounting styles, it has an above-the-board height of 4 mm (in-board mounting) or 6 mm (on-board mounting). Power density is 48,8 W/cm³ and the devices do not require external parts.

The B048K120T10, rated at 100 W, and B048K120T15, rated at 150 W, support lower power applications in the same V-I Chip package. Efficiency can exceed 96% and so the 100 W B048K120T10 requires no discrete heatsink in a typical application with 200 LFM of 55°C air. The B048L120T20, with its optional integral pin fins, is capable of full load operation at 200 W with 300 LFM of 80°C air.
