ISL69122 FN8970 Rev. 0.00 Digital Dual Output, 4-Phase Configurable, VR13 PWM Controller with SVID Feb 1, 2018 and 2-Bit AVID Interfaces The ISL69122 is a digital dual output, flexible multiphase Features (X+Y 4) PWM controller that is compliant with Intel 2-bit AVID interface VR13 specifications. The digital multiphase controller can Intel SVID interface be configured to support any desired phase assignments up to a maximum of four phases across the two outputs Advanced linear digital modulation scheme (X and Y). For example, 3+1, 2+2, or even single output Zero latency synthetic current control for excellent operation as a 4+0 configuration are supported. With a high frequency current balance flexible X+Y 4 phase assignment along with PMBus and AVID interfaces, the ISL69122 is ideal for controlling the Auto phase add/drop for excellent load vs microprocessor core, memory, and system rails of Intel efficiency profile VR13 platforms. Excellent DVID performance The ISL69122 uses the proprietary Renesas digital linear Dual edge modulation for faster transient response synthetic current modulation scheme to achieve the Flexible phase assignment from 0 to 4 phases per industrys best combination of transient response and ease output of tuning while addressing the challenges of powering the latest generation of Intel microprocessors. Device Up to 1MHz operation for high density designs configuration and telemetry monitoring are accomplished Diode braking for overshoot reduction using the intuitive Renesas PowerNavigator software. Diode emulation and automatic phase add/drop features Diode emulation for enhanced light-load efficiency allow the user to extract maximum efficiency from the Differential remote voltage sensing supports 0.5% converter regardless of load conditions. closed-loop system accuracy over load, line, and The ISL69122 supports a comprehensive fault temperature management system to enable the design of highly reliable Highly accurate current sensing for excellent load line systems. From an overcurrent protection scheme including regulation and accurate OCP peak and average detection, to the configurable Supports ISL99227 60A smart power stages power-good and catastrophic fault protection flags, any need is accommodated. Supports DCR sense with integrated temperature compensation With minimal external components, the ability to store eight configurations, robust fault management, and highly Comprehensive fault management enables high accurate regulation capability, implementing a reliability systems high-performance, multiphase regulator has never been Pulse-by-pulse phase current limiting easier.
