Single-Phase PWM Regulator for IMVP-6™ Mobile  
CPUs  
ISL62884C  
Features  
• Precision Core Voltage Regulation  
- 0.5% System Accuracy Over-Temperature  
- Enhanced Load Line Accuracy  
The ISL62884C is a single-phase PWM buck regulator for  
miroprocessor core power supply. It uses an integrated  
gate drivers to provide a complete solution. The PWM  
modulator of ISL62884C is based on Intersil's Robust  
• Voltage Identification Input  
- 7-Bit VID Input, 0V to 1.500V in 12.5mV Steps  
- Supports VID Changes On-The-Fly  
3
Ripple Regulator (R ™) technology. Compared with  
3
traditional modulators, the R ™ modulator commands  
variable switching frequency during load transients,  
achieving faster transient response. With the same  
modulator, the switching frequency is reduced at light  
load, increasing the regulator efficiency.  
• Supports Multiple Current Sensing Methods  
- Lossless Inductor DCR Current Sensing  
- Precision Resistor Current Sensing  
The ISL62884C is fully compliant with IMVP-6™  
specifications. It responds to DPRSLPVR signals by  
entering/exiting diode emulation mode. It reports the  
regulator output current through the IMON pin. It senses  
the current by using either discrete resistor or inductor  
DCR whose variation over-temperature can be thermally  
compensated by a single NTC thermistor. It uses  
differential remote voltage sensing to accurately regulate  
the processor die voltage. The adaptive body diode  
conduction time reduction function minimizes the body  
diode conduction loss in diode emulation mode.  
User-selectable overshoot reduction function offers an  
option to aggressively reduce the output capacitors as  
well as the option to disable it for users concerned about  
increased system thermal stress.  
• Superior Noise Immunity and Transient Response  
• Current Monitor  
• Differential Remote Voltage Sensing  
• High Efficiency Across Entire Load Range  
• Integrated Gate Driver  
• Adaptive Body Diode Conduction Time Reduction  
• User-selectable Overshoot Reduction Function  
• Small Footprint 28 Ld 4x4 TQFN Package  
• Pb-Free (RoHS Compliant)  
Applications*(see page 29)  
• Notebook Core Voltage Regulator  
• Notebook GPU Voltage Regulator
