GENERAL DESCRIPTION
The LD7301/02 is an ACPI-compliant controller for the applications of microprocessor and computers. It integrates a switch controller to generate a 5VDL from ATX power supply, a linear controller VDDQ and a bus terminator VTT controller. As well, it supports DDRI and DDRII with dual modes. The device also integrates a charge pump engine, which enables to drive a NMOS application. As well, the LD7301/02 also offers power OK status checking and reporting, under voltage detection, soft start and shutdown function necessary for complete ACPI implementation.FEATURES
