Rev. 0.00
Feb 1, 2018
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
Features
• 2-bit AVID interface
• Intel SVID interface
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.
• Advanced linear digital modulation scheme
• Zero latency synthetic current control for excellent
high frequency current balance
• Auto phase add/drop for excellent load vs
efficiency profile
• Excellent DVID performance
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.
• Dual edge modulation for faster transient response
• Flexible phase assignment from 0 to 4 phases per
output
• Up to 1MHz operation for high density designs
• Diode braking for overshoot reduction
• Diode emulation for enhanced light-load efficiency
• Differential remote voltage sensing supports 0.5%
closed-loop system accuracy over load, line, and
temperature
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.
• Highly accurate current sensing for excellent load line
regulation and accurate OCP
• Supports ISL99227 60A smart power stages
• Supports DCR sense with integrated temperature
compensation
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.
• Comprehensive fault management enables high
reliability systems
• Pulse-by-pulse phase current limiting
• Total output current protection
