Two-Phase Buck PWM Controller with
Integrated MOSFET Drivers for Intel VR11
and AMD Applications
The ISL6313 two-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.
One outstanding feature of this controller IC is its
multiprocessor 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.
The ISL6313 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 and Adaptive Phase Alignment (APA) are two
other unique features, allowing for quicker initial response to
high di/dt load transients. With this quicker initial response to
load transients, the number of output bulk capacitors can be
reduced, helping to reduce cost.
Integrated into the ISL6313 are user programmable current
sense resistors, which require only a single external resistor
to set their values. No external current sense resistors are
required. Another unique feature of the ISL6313 is the
addition of a dynamic VID compensation pin that allows
