Data Sheet

FN9284.3  
5-Bit VID Single-Phase Voltage Regulator  
with Power Monitor 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 ISL6263A IC is a Single-Phase Synchronous-Buck  
PWM voltage regulator featuring Intersil’s Robust Ripple  
3
Regulator (R ) Technology™. The ISL6263A is an  
• Real-time GPU Power Monitor Output  
• Applications Up to 25A  
®
implementation of the Intel Mobile Voltage Positioning  
(IMVP) protocol for GPU Render Engine core power.  
Integrated power monitor, droop amplifier, MOSFET drivers,  
and bootstrap diode result in smaller implementation area and  
lower component cost.  
• 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  
• 5-bit Voltage Identification Input (VID)  
- 1.28750 to 0.41200V  
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. For maximum conversion  
efficiency, the ISL6263A automatically enters diode  
emulation mode (DEM) should the inductor current attempt  
to flow negative. DEM is highly configurable and easy to  
setup. A PWM filter can be enabled that prevents the  
switching frequency from entering the audible spectrum as a  
result of extremely light load while in DEM.  
- 25.75mV Steps  
- Sequential or Non-sequential VID Change On-the-fly  
• Configurable PWM Modes  
- Forced Continuous Conduction Mode  
- Automatic Entry and Exit of Diode Emulation Mode  
- Selectable Audible Frequency PWM Filter  
• Integrated MOSFET Drivers and Bootstrap Diode  
• Choice of Current Sensing Schemes  
- Lossless inductor DCR Current Sensing  
- Precision Resistive Current Sensing  
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  
ISL6263A requires only one capacitor for both the soft-start  
slew-rate and 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.  
• Overvoltage, Undervoltage, and Overcurrent Protection  
• Pb-free (RoHS compliant)
