FN6359.1

Two-Phase Core Controller for AMD

Mobile Turion CPUs

Features

• Precision Two-phase Core Voltage Regulator

- 0.5% system accuracy over temperature

The ISL6264 is a two-phase buck converter regulator with

embedded gate drivers. The two-phase buck converter uses

two interleaved channels to effectively double the output

voltage ripple frequency and thereby reduce output voltage

ripple amplitude with fewer components, lower component

cost, reduced power dissipation, and smaller real estate

area. ISL6264 can also be configured as single-phase

controller for low power CPU applications.

• Voltage positioning with Adjustable Load Line and Offset

• Internal Gate Driver with 2A Driving Capability

• Dynamic Phase Adding/Dropping

• Differential Current Sensing: DCR or resistor

• Microprocessor Voltage Identification Input

- 6-Bit VID Input

The heart of the ISL6264 is the patented R³Technology™,

Intersil’s Robust Ripple Regulator modulator. Compared with

the traditional multi-phase buck regulator, the R³

Technology™ has the fastest transient response. This is due

to the R³modulator commanding variable switching

frequency during a load transient.

- 0.775V to 1.55V in 12.5mV Steps

- 0.375V to 0.7625V in 25mV Steps

• Adjustable Reference-Voltage Offset

• Audio Filter Enable/Disable

• User Programmable Switching Frequency

• Differential Remote CPU Die Voltage Sensing

• Static and Dynamic Current Sharing

To boost battery life, the ISL6264 supports PSI_L for deeper

sleep mode via automatically enabling different operation

modes. At heavy load operation of the active mode, the

regulator commands the two phase continuous conduction

mode (CCM) operation. While the PSI_L is asserted during

the deeper sleep mode, the ISL6264 smoothly disables one

phase and operates in a one-phase diode emulation mode

(DE) to maximize the efficiency at light load.

• Overvoltage, Undervoltage, and Overcurrent Protection

A 6-bit digital-to-analog converter (DAC) allows dynamic

adjustment of the core output voltage from 0.375V to 1.55V.

A 0.5% system accuracy of the core output voltage over

temperature at active mode is achieved by the ISL6264.

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.

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 AMD mobile CPU

specifications. Current sensing can be realized using either

lossless inductor DCR sensing or precision resistor sensing.

A single NTC thermistor network thermally compensates the

gain and the time constant of the DCR variations.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
