Two-Phase Multiphase Buck PWM

Features

• Integrated Two-Phase Power Conversion

Controller with Integrated MOSFET Drivers

The ISL6563 two-phase PWM control IC provides a

precision voltage regulation system for advanced

microprocessors. Multiphase power conversion is a marked

departure from single phase converter configurations

employed to satisfy the increasing current demands of

modern microprocessors and other electronic circuits. By

distributing the power and load current, implementation of

multiphase converters utilize smaller and lower cost

transistors with fewer input and output capacitors. These

reductions accrue from the higher effective conversion

frequency with higher frequency ripple current due to the

phase interleaving process of this topology.

• Both 5V and 12V Conversion

• Precision Channel Current Sharing

- Loss Less Current Sampling - Uses r

DS(ON)

• Precision Output Voltage Regulation

- ±1% System Accuracy Over Temperature (Commercial)

• Microprocessor Voltage Identification Inputs

- Up to a 6-Bit DAC

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

Hammer DAC codes

- Resistor-Programmable Droop Voltage

• Fast Transient Recovery Time

Outstanding features of this controller IC include

programmable VID codes compatible with Intel VRM9,

VRM10, as well as AMD’s Hammer microprocessors, along

with a system regulation accuracy of ±1%. The droop

characteristic, used to reduce the overshoot or undershoot of

the output voltage, is easily programmed with a single resistor.

• Overcurrent Protection

• Improved, Multi-tiered Overvoltage Protection

• Capable of Start-up into a Pre-Charged Output

• QFN Package:

- Compliant to JEDEC PUB95 MO-220

QFN - Quad Flat No Leads - Package Outline

Important features of this controller IC include a set of

sophisticated overvoltage and overcurrent protection.

Overvoltage results in the converter turning the lower

MOSFETs ON to clamp the rising output voltage and protect

the microprocessor. Like other Intersil multiphase

controllers, the ISL6563 uses cost and space-saving

- Near Chip Scale Package footprint, which improves

PCB efficiency and has a thinner profile

• Pb-Free Available (RoHS Compliant)

sensing for channel current balance, dynamic

DS(ON)

voltage positioning, and overcurrent protection. Channel

current balancing is automatic and accurate with the

integrated current-balance control system. Overcurrent

protection can be tailored to any application with no need for

additional parts. These features provide advanced protection

for the microprocessor and power system.

1. Intersil Pb-free 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.

2. Add “-T” suffix for Tape and Reel.

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