Multiphase PWM Regulator for IMVP-6+

Mobile CPUs

Features

• Precision Multiphase Core Voltage Regulation

- 0.5% System Accuracy Over Temperature

- Enhanced Load Line Accuracy

The ISL6260C is a multiple phase PWM buck regulator for

miroprocessor core power supply. The multiple phase

implementation results in better system performance, superior

thermal management, lower component cost, reduced power

dissipation, and smaller implementation area. The ISL6260C

multiphase controller together with ISL6208 external gate

drivers provide a complete solution to power Intel's mobile

microprocessors. The PWM modulator of ISL6260C is based

• Microprocessor Voltage Identification Input

- 7-Bit VID Input

- 0.300V to 1.500V in 12.5mV Steps

- Supports VID Changes On-The-Fly

• Multiple Current Sensing Approaches Supported

- Lossless DCR Current Sensing

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

Compared with the traditional multiphase buck regulator, the R

modulator commands variable switching frequency during load

transients, which achieves faster transient response. With the

same modulator, the switching frequency is reduced at light

load conditions resulting higher operation efficiency.

- Precision Resistive Current Sensing

• Supports PSI# and Narrow VDC for Enhanced Battery Life

(EBL) Initiatives

• Superior Noise Immunity and Transient Response

• Power Monitor and Thermal Monitor

• Differential Remote Voltage Sensing

• High Efficiency Across Entire Load Range

• Programmable 1, 2 or 3 Power Channels

• Excellent Dynamic Current Balance between Channels

• Small Footprint 40 Ld 6x6 QFN Package

• IMVP-6+ Compliant

Intel Mobile Voltage Positioning (IMVP) reduces power

dissipation for Intel Pentium processors. The ISL6260C is

designed to be completely compliant with IMVP-6+

specifications. ISL6260C responds to PSI# signal by adding or

dropping PWM2 and adjusting overcurrent protection

accordingly. To reduce audible noise, the DPRSLPVR signal

can be used to reduce output voltage slew rates when entering

and exiting Deeper Sleep State according to Intel specification.

The ISL6260C has several other key features. ISL6260C

reports output power through a power monitor pin. Current

sense can be achieved by using either inductor DCR or

discrete precision resistor. In the case of DCR current

sensing, a single NTC thermistor is used to thermally

compensate the inductor DCR variation with temperature. A

unity gain, differential amplifier is available for remote

voltage sensing. This allows the voltage on the CPU die to

be accurately regulated to meet Intel IMVP-6+

specifications.

• Pb-Free (RoHS Compliant)

Applications

• Mobile Laptop Computers
