controller designed to be compliant with Intel VR13
specifications. The digital multiphase controller can be
configured to support any desired phase assignments on the
second output channel, up to a maximum of six phases. The
ISL69127 supports the SVID interface along with PMBus v1.3
specifications, making it ideal for controlling the
microprocessor core, memory, and system agent rails of Intel
VR13 platforms.
The ISL69127 uses the Renesas proprietary digital linear
synthetic current modulation scheme to achieve the industry’s
best combination of transient response and ease of tuning
while addressing the challenges of powering the latest
generation of Intel microprocessors. Device configuration and
telemetry monitoring are accomplished using the intuitive
PowerNavigator™ software. Diode emulation and automatic
phase add/drop features allow the user to extract maximum
efficiency from the converter regardless of load conditions.
The ISL69127 supports a comprehensive fault management
system to enable the design of highly reliable systems. From
an overcurrent protection scheme including peak and average
detection, to the configurable power-good and catastrophic
fault protection flags, any need is accommodated.
With minimal external components, the ability to store eight
configurations, robust fault management, and highly accurate
regulation capability, implementing a high-performance,
multiphase regulator has never been easier.

the incorporation or any other use of the circuits, software, and information in the design of your product or system. Renesas Electronics disclaims any and all liability for any losses and damages incurred by
you or third parties arising from the use of these circuits, software, or information.
2.
Renesas Electronics hereby expressly disclaims any warranties against and liability for infringement or any other claims involving patents, copyrights, or other intellectual property rights of third parties, by or
arising from the use of Renesas Electronics products or technical information described in this document, including but not limited to, the product data, drawings, charts, programs, algorithms, and application
examples.

4.
No license, express, implied or otherwise, is granted hereby under any patents, copyrights or other intellectual property rights of Renesas Electronics or others.
You shall not alter, modify, copy, or reverse engineer any Renesas Electronics product, whether in whole or in part. Renesas Electronics disclaims any and all liability for any losses or damages incurred by
you or third parties arising from such alteration, modification, copying or reverse engineering.
5.
Renesas Electronics products are classified according to the following two quality grades: “Standard” and “High Quality”. The intended applications for each Renesas Electronics product depends on the
product’s quality grade, as indicated below.
"Standard":
Computers; office equipment; communications equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools; personal electronic
equipment; industrial robots; etc.
"High Quality": Transportation equipment (automobiles, trains, ships, etc.); traffic control (traffic lights); large-scale communication equipment; key financial terminal systems; safety control equipment; etc.
Unless expressly designated as a high reliability product or a product for harsh environments in a Renesas Electronics data sheet or other Renesas Electronics document, Renesas Electronics products are
not intended or authorized for use in products or systems that may pose a direct threat to human life or bodily injury (artificial life support devices or systems; surgical implantations; etc.), or may cause
serious property damage (space system; undersea repeaters; nuclear power control systems; aircraft control systems; key plant systems; military equipment; etc.). Renesas Electronics disclaims any and all
liability for any damages or losses incurred by you or any third parties arising from the use of any Renesas Electronics product that is inconsistent with any Renesas Electronics data sheet, user’s manual or
other Renesas Electronics document.
6.
When using Renesas Electronics products, refer to the latest product information (data sheets, user’s manuals, application notes, “General Notes for Handling and Using Semiconductor Devices” in the
reliability handbook, etc.), and ensure that usage conditions are within the ranges specified by Renesas Electronics with respect to maximum ratings, operating power supply voltage range, heat dissipation
characteristics, installation, etc. Renesas Electronics disclaims any and all liability for any malfunctions, failure or accident arising out of the use of Renesas Electronics products outside of such specified
ranges.
7.
Although Renesas Electronics endeavors to improve the quality and reliability of Renesas Electronics products, semiconductor products have specific characteristics, such as the occurrence of failure at a
certain rate and malfunctions under certain use conditions. Unless designated as a high reliability product or a product for harsh environments in a Renesas Electronics data sheet or other Renesas
Electronics document, Renesas Electronics products are not subject to radiation resistance design. You are responsible for implementing safety measures to guard against the possibility of bodily injury, injury
or damage caused by fire, and/or danger to the public in the event of a failure or malfunction of Renesas Electronics products, such as safety design for hardware and software, including but not limited to
redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because the evaluation of microcomputer software alone is very difficult
and impractical, you are responsible for evaluating the safety of the final products or systems manufactured by you.
