Digital Dual Output, 7-Phase Configurable, VR13/IMVP8 PWM Controller

The ISL69128 is a digital dual output, flexible multiphase

Features

(X+Y ≤ 7) PWM controller designed to be compliant with Intel

• Advanced linear digital modulation scheme

VR13 and IMVP8 specifications. The digital multiphase

controller can be configured to support any desired phase

assignments up to a maximum of seven phases across the two

outputs (X and Y). For example, 6+1, 5+2, 4+2, 3+3, 3+2, or

even single output operation as a 7+0 configuration are

supported. The ISL69128, with a flexible X+Y ≤ 7 phase

assignment, supports SVID interface along with PMBus 1.3

specifications, making it ideal for controlling the

- Zero latency synthetic current control for excellent HF

current balance

- Auto phase add/drop with a boot refresh function for

excellent load vs efficiency profile

- Dual edge modulation for faster transient response

- Excellent DVID performance

microprocessor core, memory, and system rails for Intel VR13

or IMVP8 platforms.

• Flexible phase assignment from 0 to 7 phases per output

• Up to 1MHz switching frequency operation for high density

designs

The ISL69128 uses a 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 monitoring

are accomplished through the intuitive Renesas

PowerNavigator™ application. Diode emulation and automatic

phase add/drop features allow the user to extract maximum

efficiency from the converter regardless of load conditions.

• 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

• Highly accurate current sensing for excellent load line

regulation and accurate OCP

The ISL69128 supports a comprehensive fault management

system to enable the design of highly reliable systems. From a

multitiered overcurrent protection scheme to the configurable

power-good and catastrophic fault protection flags, almost any

need is accommodated.

- Supports ISL99227 60A smart power stage

- Supports DCR sense with integrated temperature

compensation

• Supports phase doubler (ISL6617A) for up to 14-phase

operation

With minimal external components, easy configuration, 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

- Output and input OV/UV protection

- Open voltage sense detect

Applications

• Core, memory and system rails for Intel VR13 and IMVP8

based processors

- Black box recording capability for faults

- High performance servers core or memory rail

- High performance graphics rail

- Configurable Catastrophic Failure Protection (CFP) flag

output

- High-end desktop with overclocking option

• Intuitive configuration using PowerNavigator

• Networking, data center, storage, and general purpose

• SMBus/PMBus v1.3 compatible

- Up to 2MHz bus interface

- NVM to store up to 8 configurations

• Pb-free (RoHS compliant)
