ISL62771  
FN8321  
Rev 4.00  
November 18, 2015  
Multiphase PWM Regulator for AMD Fusion™ Mobile CPUs Using SVI 2.0  
The ISL62771 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 ISL62771 controller supports two  
Voltage Regulators (VRs) with three integrated gate drivers. The  
Core VR supports 2-, or 1-phase configurations while the  
Northbridge VR supports 1-phase operation. 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.  
- Serial VID clock frequency range 100kHz to 25MHz  
• Dual output controller with integrated drivers  
• 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  
• Programmable 1- or 2-phase for the core output  
• Adaptive body diode conduction time reduction  
• Superior noise immunity and transient response  
• Output current and voltage telemetry  
The ISL62771 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.  
• Differential remote voltage sensing  
Applications  
• High efficiency across entire load range  
• AMD fusion CPU/GPU and APU core power  
• Programmable VID offset and droop on both outputs  
• Programmable switching frequency for both outputs  
• Excellent dynamic current balance between phases  
• Protection: OCP/WOC, OVP, PGOOD and thermal monitor  
• Notebook computers  
Related Literature  
• TB497, “Disabling the North Bridge Regulator on the  
ISL62771”  
• Small footprint 40 Ld 5x5 TQFN package  
- Pb-free (RoHS compliant)
