Fujitsu Develops LSI For Ultra Mobile PCs

Fujitsu Microelectronics Asia Pte Ltd (FMAL) has developed one-chip system power management LSI for ultra-mobile PCs (UMPCs), to supply power to the system, memory and chipsets in UMPCs. MB39C308 complies with the upcoming version of the Low Power Intel Architecture (LPIA) specification proposed by Intel as a low-power platform for UMPCs.

MB39C308 meets the LPIA platform requirement of a six-channel DC/DC converter control circuit, while integrating other peripheral components onto the chip.

By using Laterally Diffused MOS (LDMOS) technology and revising the transistor structure, MB39C308 claims to supply power from a lithium-ion battery at high-efficiency rates without dispersion. The DC/DC converter control circuits incorporated in the chip generate voltages across six different channels and support power for memory, the chipset and external systems such as wireless LAN, as required in the 2008 version of the LPIA platform.
