FN6455.0
Single-Phase Buck PWM Controller with
Integrated MOSFET Drivers for Intel VR11
and AMD Applications
The ISL6314 single-phase PWM control IC provides a
precision voltage regulation system for advanced
microprocessors. This controller IC maintains the same
features as the multi-phase product family, but reduces the
output to a single-phase, for lower current systems. 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 VR11 as well as AMD 5-bit and 6-bit DAC
tables. A circuit 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.
Another unique feature of the ISL6314 is the addition of a
circuit that allows optimizing compensation to be added for
flatter load transient response and well controlled dynamic
VID response.
The ISL6314 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.
Active Pulse Positioning (APP) and Adaptive Phase
Alignment (APA) are two other unique features, allowing for
quicker initial response to high di/dt load transients; the
number of output bulk capacitors can be reduced, helping to
reduce cost.
Protection features of this controller IC include a set of
sophisticated overvoltage, undervoltage, and overcurrent
protection. Furthermore, the ISL6314 includes protection
against an open circuit on the remote sensing inputs.
Combined, these features provide advanced protection for the
microprocessor and power system.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are 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.
*Add “-T” suffix for tape and reel.
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
