W83301R Preliminary 1. General Description The W83301R is an ACPI-compliant controller for microprocessor and other computer applications. In substance, the part can mainly operate in alternative configurations mode A and B – mode A provides a switch controller to generate a 5VDL voltage from ATX power supply, a linear controller – STR1 (2.5VDUAL), and a bus termination controller – 1.25 VDUAL for high speed bus such as RDRAM/DDRAM current sinking and sourcing; and mode B provides a switch controller to generate a 5VDL voltage from ATX power supply and three linear controllers for specific voltage regulations – that is STR1 (2.5VDUAL), STR2 (3....
