Four-Phase Buck PWM Controller with
Integrated MOSFET Drivers for Intel VR10,
VR11, and AMD Applications
The ISL6312 four-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
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 ISL6312 also includes advanced control loop features
for optimal transient response to load apply and removal.
One of these features is highly accurate, fully differential,
continuous DCR current sensing for load line programming
and channel current balance. Active Pulse Positioning (APP)
modulation is another unique feature, allowing for quicker
initial response to high di/dt load transients.
This controller also allows the user the flexibility to choose
between PHASE detect or LGATE detect adaptive dead time
schemes. This ability allows the ISL6312 to be used in a
multitude of applications where either scheme is required.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-
free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is
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-020.
