... GENERAL DESCRIPTION W83305S is a new power management IC which compliant ACPI specification 2.0 for desktop PC and motherboard. The chip regulates two most voltage-relative powers for DDR SDRAM and AGP slot applications. As the two devices on board, a stable, reliable, and programmable power should be performed for higher reliability, stability, compatibility and better-performance for diverse combination of devices (RAM module and AGP card). The chip is operated basing on a simple dual-wire bus SMBus. Via SMBus control, the power for DDR SDRAM can be adjusted ranging from 2.50V to 3.00V ...
