FN9192.0
Digital Multiphase Controller
Features
• Multiphase power conversion
- 1- to 6-phase operation
The ISL6595 digital multiphase controller provides core
power for today’s high current microprocessors by driving up
to six synchronous-rectified buck-converter channels in
parallel. Interleaved timing of the channels results in a higher
ripple frequency, reducing input and output ripple. With up to
six phases, each capable of up to 2MHz operation, the
ISL6595 can be used to build DC/DC converters that provide
up to 200A with excellent efficiency, low ripple, and the
lowest component count.
• 100kHz to 2MHz switching frequency
®
• Supports Intel VR10.x and VR11.0 VID codes
®
• Supports AMD 5-bit and 6-bit VID codes
• Internal high precision voltage reference
- ±10mV voltage setpoint accuracy
• Precision digital current sense calibration
The ISL6595 utilizes digital technology to implement all
control functions, providing the ultimate in flexibility and
• Precise digital current balancing with programmable
offsets for thermal balancing

stability. The ISL6595 incorporates an industry standard I C
serial interface for control and monitoring. Through the serial
interface, the power supply designer can quickly optimize
designs and monitor parameters. The interface allows the
ISL6595 to provide digitized information for real time system
monitoring and control.
• Digitally programmable loadline and loop compensation
• Differential voltage sense
• Digital temperature sensor compensation
• Active Transient Response (ATR) enables meeting
transient requirements with reduced output capacitance
The ISL6595 provides superior loadline accuracy through
internal calibration that measures and corrects current sense
error sources upon startup. The ISL6595 has programmable
current sense temperature compensation that allows the
designer to tailor the response for best loadline accuracy
over temperature. Superior loadline accuracy reduces
component count and solution cost.

• I C interface for monitoring, control and configuration
• Internal non-volatile memory (NVM) to store custom
configurations
• Extensive fault detection capability with two user
configurable output fault pins (FAULT1, FAULT2)
- Input undervoltage
- Output under/overvoltage
- High side short
- Per phase and total output current
- Multiple internal and external temperature limits
- NVM configuration
To further reduce component count the ISL6595
incorporates patented Active Transient Response (ATR)
technology, allowing the fastest response to transient events
for reduced output capacitance.
The flexibility of the ISL6595 allows the power supply
designer to implement a wide range of solutions. When used
with industry standard power train components, the ISL6595
provides the highest performance with lowest component
count and cost.

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.
• Intelligent point-of-load (POL) power regulation
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
