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.
