Multiphase PWM Regulator for IMVP-6.5™ Mobile CPUs

and GPUs

ISL62882, ISL62882B

Features

The ISL62882 is a multiphase PWM buck regulator for

• Programmable 1- or 2-Phase CPU Mode Operation or 1-Phase

GPU Mode Operation

miroprocessor or graphics processor core power supply. The

multiphase buck converter uses interleaved phases 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 implementation area. The ISL62882 uses

two integrated gate drivers to provide a complete solution. The PWM

• Precision Multiphase Core Voltage Regulation

- 0.5% System Accuracy Over-Temperature

- Enhanced Load Line Accuracy

• Microprocessor Voltage Identification Input

- 7-Bit VID Input, 0V to 1.500V in 12.5mV Steps

- Supports VID Changes On-The-Fly

modulator is based on Intersil's Robust Ripple Regulator (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 Multiple Current Sensing Methods

- Lossless Inductor DCR Current Sensing

- Precision Resistor Current Sensing

• Supports PSI# and DPRSLPVR modes

The ISL62882 can be configured as CPU or graphics Vcore controller

and is fully compliant with IMVP-6.5™ specifications. It responds to

PSI# and DPRSLPVR signals by adding or dropping Phase 2,

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 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 unique split LGATE function

further increases light load efficiency. 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. The ISL62882 offers the

FB2 function to optimize 1-phase performance.

• Superior Noise Immunity and Transient Response

• Current Monitor and Thermal Monitor

• Differential Remote Voltage Sensing

• High Efficiency Across Entire Load Range

• Programmable 1- or 2-Phase Operation

• Two Integrated Gate Drivers

• Excellent Dynamic Current Balance Between Phases

• Split LGATE1 Drivers Increases Light Load Efficiency

• FB2 Function Optimizes 1-Phase Mode Performance

• Adaptive Body Diode Conduction Time Reduction

• User-selectable Overshoot Reduction Function

• Small Footprint 40 Ld 5x5 or 48 Ld 6x6 TQFN Packages

• Pb-Free (RoHS Compliant)

The ISL62882B has the same functions as the ISL62882, but

comes in a different package.

Applications

• Notebook Core Voltage Regulator

• Notebook GPU Voltage Regulator
