GENERAL DESCRIPTION
RT8801 is one of RichTek CPU core power solutions which integrates a specific series programming interface for the controller operation configuration. There are several registers implemented for the specific parameters configuration including VID for core power, and signal for load current indication. User can program the configuration of the parameters easily via the specific programming interface. With the implementation of RT8801, the part provides more flexibility and feature for customers advanced segment product design. The RT8801 applies the DCR sensing technology newly as well; with such a topology, the RT8801 extracts the DCR of output inductor as sense component to deliver a more precise load line regulation and better thermal balance for next generation processor application. For current sense setting, droop tuning, VCORE initial offset and over current protection are independent to compensation circuit of voltage loop. The feature greatly facilitates the flexibility of CPU power supply design and tuning.
