Data Sheet  
June 10, 2010  
FN9213.2  
5-Bit VID Single-Phase Voltage Regulator  
for IMVP-6+ Santa Rosa GPU Core  
Features  
• Precision single-phase core voltage regulator  
- 0.5% system accuracy 0°C to +100°C  
- Differential remote GPU die voltage sensing  
- Differential droop voltage sensing  
The ISL6263 IC is a Single-Phase Synchronous-Buck PWM  
voltage regulator featuring Intersil’s Robust Ripple Regulator  
3
(R ) Technology™. The ISL6263 is an implementation of the  
®
Intel Mobile Voltage Positioning (IMVP) protocol for GPU  
• Applications up to 25A  
Render Engine core power. Integrated MOSFET drivers,  
bootstrap diode, and droop amplifier result in lower  
component cost and smaller implementation area.  
• Input voltage range: +5.0V to +25.0V  
• Programmable PWM frequency: 200kHz to 500kHz  
• Pre-biased output start-up capability  
3
Intersil’s R Technology™ combines the best features of  
both fixed-frequency PWM and hysteretic PWM, delivering  
excellent light-load efficiency and superior load transient  
response by commanding variable switching frequency  
during the transitory event.  
• 5-bit voltage identification input (VID)  
- 1.28750 to 0.41200V  
- 25.75mV steps  
- Sequential or non-sequential VID change on-the-fly  
To maximize light load efficiency, the ISL6263 automatically  
transitions between continuous-conduction-mode (CCM)  
and discontinuous-conduction-mode (DCM.) During DCM  
the low-side MOSFET enters diode-emulation-mode (DEM.)  
DEM is enabled whenever a Render Suspend state has  
been set on the VID inputs. Optionally, DEM can be enabled  
for all VID states by setting the FDE pin high. The ISL6263  
has an audio filter that can be enabled in any Render  
Suspend state by pulling the AF_EN pin high. The audio  
filter prevents the PWM switching frequency from entering  
the audible spectrum due to extremely light load while in  
DEM.  
• Selectable diode emulation mode  
- Render Suspend mode only  
- Render Performance and Render Suspend mode  
• Selectable audio filter in render suspend mode  
• Integrated MOSFET drivers and bootstrap diode  
• Choice of current sensing schemes  
- Lossless inductor DCR current sensing  
- Precision resistive current sensing  
• Overvoltage, undervoltage, and overcurrent protection  
• Pb-free plus anneal available (RoHS compliant)  
The Render core voltage can be dynamically programmed  
from 0.41200V to 1.28750V by the five VID input pins  
without requiring sequential stepping of the VID states. The  
ISL6263 uses the same capacitor for the soft-start slew-rate  
and for the dynamic VID slew-rate by internally connecting  
the SOFT pin to the appropriate current source. Processor  
socket Kelvin sensing is accomplished with an integrated  
unity-gain true differential amplifier.
