Three-Phase Buck PWM Controller with

Integrated MOSFET Drivers for VRM9,

VRM10, and AMD Hammer Applications

Features

• Integrated Multi-Phase Power Conversion

- 1, 2, or 3-Phase Operation

The ISL6566 three-phase PWM control IC provides a

precision voltage regulation system for advanced

microprocessors. The integration of power MOSFET drivers

into the controller IC marks a departure from the separate

PWM controller and driver configuration of previous multi-

phase product families. By reducing the number of external

parts, this integration is optimized for a cost and space

saving power management solution.

• Precision Core Voltage Regulation

- Differential Remote Voltage Sensing

- ±0.5% System Accuracy Over Temperature

- Adjustable Reference-Voltage Offset

• Precision Channel Current Sharing

- Uses Loss-Less r

Current Sampling

DS(ON)

• Accurate Load Line Programming

- Uses Loss-Less Inductor DCR Current Sampling

Outstanding features of this controller IC include programmable

VID codes compatible with Intel VRM9, VRM10, as well as

AMD Hammer microprocessors. A unity gain, differential

amplifier is provided for remote voltage sensing, compensating

for any potential difference between remote and local grounds.

The output voltage can also be positively or negatively offset

through the use of a single external resistor.

• Variable Gate Drive Bias: 5V to 12V

• Microprocessor Voltage Identification Inputs

- Up to a 6-Bit DAC

- Selectable between Intel’s VRM9, VRM10, or AMD

Hammer DAC codes

A unique feature of the ISL6566 is the combined use of both

- Dynamic VID Technology

DCR and r

current sensing. Load line voltage

DS(ON)

• Overcurrent Protection

positioning (droop) and overcurrent protection are

accomplished through continuous inductor DCR current

• Multi-tiered Overvoltage Protection

• Digital Soft-Start

sensing, while r

current sensing is used for accurate

DS(ON)

channel-current balance. Using both methods of current

sampling utilizes the best advantages of each technique.

• Selectable Operation Frequency up to 1.5MHz Per Phase

• Pb-Free Plus Anneal Available (RoHS Compliant)

Protection features of this controller IC include a set of

sophisticated overvoltage, undervoltage, and overcurrent

protection. Overvoltage results in the converter turning the

lower MOSFETs ON to clamp the rising output voltage and

protect the microprocessor. The overcurrent protection level is

set through a single external resistor. Furthermore, the ISL6566

includes protection against an open circuit on the remote

sensing inputs. Combined, these features provide advanced

protection for the microprocessor and power system.

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.
