Multiphase PWM Regulator for IMVP-6.5™ Mobile CPUs  
ISL62883, ISL62883B  
Features  
The ISL62883 is a multiphase PWM buck regulator for  
• Precision Multiphase Core Voltage Regulation  
- 0.5% System Accuracy Over-Temperature  
- Enhanced Load Line Accuracy  
miroprocessor core power supply. The multiphase buck converter  
uses interleaved phase to reduce the total output voltage ripple with  
each phase carrying a portion of the total load current, providing  
better system performance, superior thermal management, lower  
component cost, reduced power dissipation, and smaller  
• Microprocessor Voltage Identification Input  
- 7-Bit VID Input, 0.300V to 1.500V in 12.5mV Steps  
- Supports VID Changes On-The-Fly  
implementation area. The ISL62883 uses two integrated gate  
drivers and an external gate driver to provide a complete solution.  
The PWM modulator is based on Intersil's Robust Ripple Regulator  
• Supports Multiple Current Sensing Methods  
- Lossless Inductor DCR Current Sensing  
- Precision Resistor Current Sensing

(R ) technology™. Compared with 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 PSI# and DPRSLPVR modes  
• Superior Noise Immunity and Transient Response  
• Current Monitor and Thermal Monitor  
• Differential Remote Voltage Sensing  
The ISL62883 is fully compliant with IMVP-6.5™ specifications. It  
responds to PSI# and DPRSLPVR signals by adding or dropping  
PWM3 and Phase-2 respectively, adjusting overcurrent protection  
threshold accordingly, and entering/exiting diode emulation mode.  
It reports the regulator output current through the IMON pin. It  
senses the current by using either a 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. In 2-Phase configuration, the  
ISL62883 offers the FB2 function to optimize 1-Phase  
performance.  
• High Efficiency Across Entire Load Range  
• Programmable 1-, 2- or 3-Phase Operation  
• Two Integrated Gate Drivers  
• Excellent Dynamic Current Balance Between Phases  
• FB2 Function in 2-Phase Configuration to Optimize 1-Phase  
Performance  
• Adaptive Body Diode Conduction Time Reduction  
• User-selectable Overshoot Reduction Function  
• Small Footprint 40 Ld 5x5 or 48 Ld 6x6 TQFN Package  
• Pb-Free (RoHS Compliant)  
Applications  
• Notebook Computers  
The ISL62883B has the same functions as the ISL62883, but  
comes in a different package.
