DescriptionThe PI1004 IC combines a Voltage Identification DigitalInput (VID) controlled reference with control andsupervisory functions to accurately set the regulatoroutput voltage at the point of load, for isolated and CPUDC-DC converters in desktop and server applications. The PI1004 feature set is intended to be used in conjunctionwith a variety of power architectures, including FactorizedPower Architecture (FPA), to provide CPU power inaccordance with Intel® VR10.X requirements. The featureset includes a precision error amplifier for remoteifferential sensing of the output voltage, a six bitprogrammable VID reference voltage output with 12.5mV resolution, and flexible adaptive voltage positioning.The regulation voltage can also be shifted below the VIDrange with a programmable offset current. The controllerincludes an over-voltage indicator output, an opencollector power-good output, under-voltage lockout andan externally programmable soft start.
The PI1004 is available in two options; PI1004-1:Programmable VID offset current and no OVP output. TheVID offset current is used to create an offset to the DAC utput. PI1004-2: OVP output and no VID offset.
