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

Combined, these features provide advanced protection for the
microprocessor and power system.
NOTE: 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.
