Digital, Dual Output, 4-Phase Configurable, VR13/IMVP8 PWM Controller FN8916
Rev.1.00
May 22, 2017 The ISL69133 is a digital, dual output, flexible, multiphase (X+Y ≤ 4) PWM controller designed to be compliant with
Intel VR13/IMVP8 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, PMBus, and
SerialVID (SVID) interfaces, the ISL69133 is ideal for controlling the microprocessor core, memory, and system rails
of Intel VR13/IMVP8 platforms.
The ISL69133 uses Intersil’s 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 Intersil’s
intuitive PowerNavigatorв„ў GUI. Diode emulation and automatic phase add/drop features allow the user to extract
maximum efficiency from the converter regardless of load conditions.
The ISL69133 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. Features 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 Dynamic Voltage Identification (DVID) performance 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 В±0.5% closed-loop system accuracy over load, line, and temperature Highly accurate current sensing for excellent load-line regulation and accurate OCP Supports ISL99227 60A smart power stages Supports …
