Data Sheet

December 27, 2004

FN9156.2

Multi-Phase PWM Controller with Linear

6-bit DAC Capable of Precision r or

Features

• Precision Multi-Phase Core Voltage Regulation

- Differential Remote Voltage Sensing

- ±0.5% System Accuracy

DS(ON)

DCR Differential Current Sensing

The ISL6564 is a Multi-phase PWM controller which controls

microprocessor core voltage regulation by driving up to 4

synchronous-rectified buck channels. It features a high

bandwidth control loop to provide optimal response to the load

transients. With switching frequency up to 1.5MHz per phase,

the ISL6564 based voltage regulator requires minimum

components and PCB area in DC/DC converter application.

- Adjustable Reference-Voltage Offset

• Precision r

DS(ON)

or DCR Current Sensing

- Accurate Load-Line Programming

- Accurate Channel-Current Balancing

- Differential Current Sense

- Low-Cost, Lossless Current Sensing

The ISL6564 senses current by utilizing patented techniques

• Internal Shunt Regulator for 5V or 12V Biasing

to measure the voltage across the on resistance, r

, of

DS(on)

the lower MOSFETs or DCR of the output inductor during

their conduction intervals. Current sensing provides the

needed signals for precision droop, channel-current

balancing, and overcurrent protection.

• Microprocessor Voltage Identification Input

- Self clocked Dynamic VID™ control technology

- 6-Bit VID Input

- 0.525V to 1.300V in 12.5mV Steps

A unity gain, differential amplifier is provided for remote

voltage sensing. Any potential difference between remote

and local grounds can be completely eliminated using the

remote-sense amplifier. Eliminating ground differences

improves regulation and protection accuracy. The threshold-

sensitive enable input is available to accurately coordinate

the start up of the ISL6564 with any other voltage rail.

Dynamic-VID™ technology allows seamless on-the-fly VID

changes. The offset pin allows accurate voltage offset

settings that are independent of VID setting. The ISL6564

uses a 5V bias and has a built-in shunt regulator to allow

12V bias using only a small external limiting resistor.

• Threshold-Sensitive Enable Function for power

sequencing control

• Overcurrent Protection

• Overvoltage Protection

- No Additional External Components Needed

- OVP Pin to drive Crowbar Device

• 1, 2, 3, or 4 Phase Operation

• Up to 1.5MHz per phase Operation (>6MHz Ripple)

• QFN Package

- Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat

No Leads - Product Outline

Ordering Information

- QFN Near Chip Scale Package Footprint; Improves

PCB Efficiency, Thinner in Profile

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.

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