Rev 1.00  
Mar 8, 2012  
Multiphase PWM Regulator for AMD Fusion™ Mobile CPUs Using SVI 2.0  
The ISL6277 is fully compliant with AMD Fusion™ SVI 2.0 and  
Features  
provides a complete solution for microprocessor and graphics  
• Supports AMD SVI 2.0 Serial Data Bus Interface  
processor core power. The ISL6277 controller supports two  
Voltage Regulators (VRs) with three integrated gate drivers and  
two optional external drivers for maximum flexibility. The Core VR  
can be configured for 3-, 2-, or 1-phase operation while the  
Northbridge VR supports 2- or 1-phase configurations. The two  
VRs share a serial control bus to communicate with the AMD CPU  
and achieve lower cost and smaller board area compared with  
two-chip solutions.  
• Dual Output Controller with Integrated Drivers  
- Two Dedicated Core Drivers  
- One Programmable Driver for Either Core or Northbridge  
• Precision Voltage Regulation  
- 0.5% System Accuracy Over-Temperature  
- 0.5V to 1.55V in 6.25mV Steps  
- Enhanced Load Line Accuracy  
The PWM modulator is based on Intersil’s Robust Ripple  
Regulator R3 Technology™. Compared to traditional modulators,  
the R3 modulator can automatically change switching frequency  
for faster transient settling time during load transients and  
improved light load efficiency.  
• Supports Multiple Current Sensing Methods  
- Lossless Inductor DCR Current Sensing  
- Precision Resistor Current Sensing  
The ISL6277 has several other key features. Both outputs  
support DCR current sensing with single NTC thermistor for  
DCR temperature compensation or accurate resistor current  
sensing. Both outputs utilize remote voltage sense, adjustable  
switching frequency, OC protection and power good.  
• Programmable 1-, 2- or 3-Phase for the Core Output and  
1- or 2-Phase for the Northbridge Output  
• Adaptive Body Diode Conduction Time Reduction  
• Superior Noise Immunity and Transient Response  
• Output Current Monitor and Thermal Monitor  
• Differential Remote Voltage Sensing  
Applications  
• AMD Fusion CPU/GPU Core Power  
• High Efficiency Across Entire Load Range  
• Programmable Slew Rate  
• Notebook Computers  
• Programmable VID Offset and Droop on Both Outputs  
• Programmable Switching Frequency for Both Outputs  
• Excellent Dynamic Current Balance Between Phases  
• OCP/WOC, OVP, PGOOD, and Thermal Monitor  
• Small Footprint 48 Ld 6x6 QFN Package  
- Pb-Free (RoHS Compliant)
