ISL69122
Digital Dual Output, 4-Phase Configurable, VR13 PWM Controller with SVID
and 2-Bit AVID Interfaces
The
ISL69122
is a digital dual output, flexible multiphase
(X+Y ≤ 4) PWM controller that is compliant with Intel
VR13 specifications. The digital multiphase controller can
be configured to support any desired phase assignments up
to a maximum of four phases across the two outputs
(X and Y). For example, 3+1, 2+2, or even single output
operation as a 4+0 configuration are supported. With a
flexible X+Y ≤ 4 phase assignment along with PMBus and
AVID interfaces, the ISL69122 is ideal for controlling the
microprocessor core, memory, and system rails of Intel
VR13 platforms.
The ISL69122 uses the proprietary Renesas 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 Renesas 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 ISL69122 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.

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

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
