ISL6566

Three-Phase Buck PWM Controller with Integrated MOSFET Drivers for VRM9,

VRM10, and AMD Hammer Applications

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.

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.

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

DCR and r

DS(ON)

current sensing. Load line voltage

positioning (droop) and overcurrent protection are

accomplished through continuous inductor DCR current

sensing, while r

DS(ON)

current sensing is used for accurate

channel-current balance. Using both methods of current

sampling utilizes the best advantages of each technique.

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.
