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. The DAC output of RT8801 supports VRD10.x with 6-bit VID input, precise initial value & smooth VCORE transient at VID jump. The IC monitors the VCORE voltage for over-voltage protection. Soft-start, over-current protection and programmable under-voltage lockout are also provided to assure the safety of microprocessor and power system. The RT8801 comes to the package of VQFN-32L 5x5.
