First highly integrated power-management IC for DDR cache-memory battery backup eliminates multiple discrete components in exist

Maxim Integrated Products introduces the DS2731 integrated power-management IC (PMIC) for DDR cache-memory backup. This PMIC integrates a single-cell Li+ charger, power-steering system to control switchover between system power and battery power, and a 2MHz synchronous buck regulator that "regulates" the DDR memory supply. This unprecedented level of integration eliminates over 15 separate components in existing solutions, thus saving both cost and space. The DS2731 is compatible with the PCI Express 12V power rail in DDRII and DDRIII, and is therefore well suited for RAID server/system memory cards, as well as RAID on motherboard (ROMB) and modular RAID on motherboard (MROMB) systems.
