uP9505  
4/3/2/1+2/1/0-Phase PWM Controller  
with SMBus Digital Interface for FM2+ CPU Core Power  
Features  
General Description  
†
†
AMD SVI2 CPU Compliant  
RCOT+TM Control Topology  
The uP9505 is anAMDSVI2 compliant desktop CPU voltage  
regulator controller that integrates a 4-phase PWM  
controller for VDDand a 2-phase controller for VDDA. The  
VDDcontroller can be configured as 4/3/2/1-phase, and the  
VDDA controller can be configured as 2/1/0-phase (0  
denotes VDDA controller is disabled) for platform power  
design flexibility. For the typical 4+2-phase application, the  
4-phase VDDcontroller has 4 PWM outputs. The 2-phase  
VDDAcontroller has 2 PWM outputs. The controller provides  
further flexible operating phase configurations to support  
6+0 or 5+1 phase application (0 denotes VDDA controller  
is disabled). The integrated SMBus interface  
programmability makes this part with high performance and  
easy design. Designer can define different power scenario  
for different current states to optimize the performance and  
efficiency.

High Accuracy DAC  
The uP9505 combines true differential output voltage sense,  
differential inductorDCR current sense, input voltage feed-  
forward sense and adaptive voltage positioning to provide  
accurately regulated power for desktop CPU. It adopts uPI  
proprietary RCOT+TM (Robust Constant On-Time) topology  
to have fast transient response and smooth mode  
transition. Similar to digital based PWM controller, the loop  
gain is also programmable by SMBus interface to achieve  
design flexibility.

OCP/UVP/OVP/Thermal Shutdown  
RoHS Compliant and Halogen Free  
The uP9505 has built-in serial interface to communicate  
withAMDSVI2 compliant CPU. It supports mode transition  
function with various operating states. This part provides  
two different VID on-the-fly slew rates, which can be  
programmed by the SMBus register.

The uP9505 provides power good indicator and selectable  
VR parameters, such as SMBus device address and Vboot  
voltage. It also provides complete fault protection functions,  
including over voltage, under voltage, over current, over  
temperature and under voltage lockout. The uP9505 is  
available in VQFN6x6-52L package.
