Microprocessor CORE Voltage Regulator

Two-Phase Buck PWM Controller

Features

• Two-phase power conversion

The ISL6560 two-phase current mode, PWM control IC

together with companion gate drivers, the HIP6601A,

HIP6602A, HIP6603A or HIP6604 and MOSFETs provides a

precision voltage regulation system for advanced

• Precision channel current sharing

• Precision CORE voltage regulation

- ±0.8% accuracy

microprocessors. Two-phase power conversion is a marked

departure from earlier single phase converter configurations

previously employed to satisfy the ever increasing current

demands of modern microprocessors. Multi-phase

converters, by distributing the power and load current,

results in 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. For example, a two phase converter operating at

350kHz per phase will have a ripple frequency of 700kHz.

Higher converter bandwidth is also achievable, resulting in

faster response to load transients.

• Microprocessor voltage identification input

- VRM 9.0 compliant

- 5-bit VID input

- 1.100 to 1.850V in 25mV steps

- Programmable “droop” voltage

• Fast transient recovery time

• Overcurrent protection

• High output ripple frequency. . . . . . . . . . . . . 100kHz to 2MHz

• Pb-Free Available (RoHS Compliant)

Applications

An outstanding feature of this controller IC includes high-

side current sensing with a single current sampling resistor

in the input line to the output MOSFET transistors. This

single current sampling resistor monitors each channels

input current assuring excellent current sharing. Current

mode control results in rapid response to changing load

demands.

• AMD Athlon™ processor voltage regulator

• Low output voltage, high current DC/DC converters

Also featured are programmable VID codes with an accuracy

of ±0.8% that range from 1.100–1.850V, and are set by the

microprocessor. Pull up currents on these VID pins

eliminates the need for external pull-up resistors.

circuit and load protection circuits which provide overvoltage

protection, overcurrent protection and undervoltage

indication.

Evaluation Platform

NOTE: 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-020C.

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