Preliminary  
RT8801  
Multi-Phase PWM Controller for CPU Core Power Supply  
with Serial Programming Interface  
General Description  
Features  
z Multi-Phase Power Conversion with Automatic  
The RT8801 is a multi-phase synchronous buck controller  
which is implemented with full control functions for Intel®  
VR10.0/10.1-compliant CPU. The RT8801 could be  
operated with 2, 3 or 4 buck switching stages operating  
in interleaved phase set automatically. The multiphase  
architecture provides high output current while maintaining  
low power dissipation on power devices and low stress  
on input and output capacitors.  
Phase Selection  
z 6-bits VRD10.x DAC Output with Active Droop  
Compensation for Fast Load Transient  
z Smooth VCORE Transition at VID Jump  
z Power Stage Thermal Balance by DCR Current  
Sense  
z Hiccup Mode Over-Current Protection  
z Adjustable Switching Frequency (50kHz to 400kHz  
per Phase)  
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.  
z Under-Voltage Lockout and Soft-Start  
z High Ripple Frequency Times Channel Number  
z 2-wires programming interface  
z Software Programmable VID  
z 32-Lead VQFN Package  
z RoHS Compliant and 100% Lead (Pb)-Free  
Applications  
z Intel® VR10.x-compliant Processors Voltage Regulator  
z Low Output Voltage, High power density DC-DC  
Converters  
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. TheDAC 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.
