ISL6566A
Three-Phase Buck PWM Controller with
Two Integrated MOSFET Drivers and One
External Driver Signal
The ISL6566A 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 ISL6566A 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
ISL6566A includes protection against an open circuit on the
remote sensing inputs. Combined, these features provide
advanced protection for the microprocessor and power system.
