The ISL6322G two-phase PWM control IC provides a
precision voltage regulation system for advanced
microprocessors and memory. The integration of power
MOSFET drivers into the controller IC marks a departure
from the separate PWM controller and driver configuration of
previous multiphase product families. By reducing the
number of external parts, this integration is optimized for a
cost and space saving power management solution.
One outstanding feature of this controller IC is its
multi-processor compatibility, allowing it to work with both Intel
and AMD microprocessors. Included are programmable VID
codes for Intel VR10, VR11, as well as AMD DAC tables. 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.
The ISL6322G includes an I2C interface, allowing the
controller to communicate with other devices over an I2C
bus. Signals sent over this bus can command the ISL6322G
to adjust the number of active phases, voltage margining
offset, phase switching frequency, overvoltage protection
levels, and can select the integrated driver adaptive dead
time scheme.
