Multiphase Core Regulator for IMVP-6

Mobile CPUs

Features

• Precision Multiphase Core Voltage Regulation

- 0.5% System Accuracy Over Temperature

- Enhanced Load Line Accuracy

The ISL6260 and ISL6260B provide microprocessor core

voltage regulation by driving up to 3 channels in parallel. The

multiphase buck converter architecture uses interleaved

channels to multiply the output voltage ripple frequency and

reduce output channel currents. The reduction in ripple results

in fewer components, lower component cost, reduced power

dissipation, and smaller implementation area. The ISL6260,

ISL6260B multiphase controller together with the ISL6208 gate

drivers form the basis for a portable power supply solution to

power Intel's next generation mobile microprocessors. The

modulator at the heart of this power system is derived from

• 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

- Precision Resistive Current Sensing

• Supports PSI# and Narrow VDC for Enhanced Battery Life

(EBL) Initiatives

• Superior Noise Immunity and Transient Response

• Thermal Monitor

Intersil's Robust Ripple Regulator technology, (R ) Compared

with the traditional multiphase buck regulator, the R

technology multiphase converter has faster transient response.

This is due to the R modulator commanding variable switching

frequency during load transients.

• Differential Remote Voltage Sensing

• High Efficiency Across Entire Load Range

• Programmable 1, 2 or 3 Power Channels

• Balanced Channel Loading Including Transients

• Small Footprint QFN 40 Lead 6x6 Package

• Pb-Free Plus Anneal Available (RoHS Compliant)

Intel Mobile Voltage Positioning is a smart voltage regulation

technology, which effectively reduces power dissipation in Intel

Pentium processors. The ISL6260 and ISL6260B support the

IMVP-6 mobile processor voltage regulation specifications.

ISL6260 and ISL6260B are pin-to-pin compatible. ISL6260B

responds to PSI# signal by adding or dropping PWM2 and

adjusting overcurrent protection accordingly. To improve

audible noise, the DPRSLPVR signal can be used to reduce

slew rates entering and exiting Deeper Sleep.

Applications

• Mobile laptop computers

TOP VIEW

The ISL6260 and ISL6260B have several other key features.

Current sensing can be done using either DCR sensing or

discrete precision resistor sensing. A single NTC thermistor

thermally compensates both the gain and time constant of

the DCR variation. A unity gain, differential amplifier is

provided for remote CPU die sensing. This allows the

voltage on the CPU die to be accurately measured and

regulated per Intel IMVP-6 specifications.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100% matte

tin plate termination finish, which are RoHS compliant and compatible

with both SnPb and Pb-free soldering operations. Intersil Pb-free

products are MSL classified at Pb-free peak reflow temperatures that

meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
