Multiphase PWM Regulator for IMVP-6.5™ Mobile

CPUs and GPUs

ISL62882, ISL62882B

Features

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

1-Phase GPU Mode Operation

The ISL62882 is a multiphase PWM buck regulator for

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

• 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

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 modulator is based on

• Supports Multiple Current Sensing Methods

- Lossless Inductor DCR Current Sensing

- Precision Resistor Current Sensing

Intersil's Robust Ripple Regulator (R ) technology™.

3™

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 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.

• 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)

Applications

• Notebook Core Voltage Regulator

• Notebook GPU Voltage Regulator

The ISL62882B has the same functions as the ISL62882,

but comes in a different package.
