Digital Dual Output, 4-Phase Configurable, VR13 PWM Controller

The ISL69125 is a digital dual output, flexible multiphase

Features

(X+Y ≤ 4) PWM controller designed to be compliant with Intel

VR13 specifications. The digital multiphase controller can be

configured to support any desired phase assignments up to a

maximum of 4 phases across the two outputs (X and Y). For

example, 3+1, 2+2, or even a single output operation as a 4+0

configuration are supported. With a flexible X+Y ≤ 4 phase

assignment along with PMBus and SVID interfaces, it 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

- 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

The ISL69125 uses the Renesas 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 the intuitive

• Diode emulation for enhanced light-load efficiency

• Differential remote voltage sensing supports ±0.5%

PowerNavigator™ software. Diode emulation and automatic

phase add/drop features allow the user to extract maximum

efficiency from the converter regardless of load conditions.

closed-loop system accuracy over load, line and temperature

• Highly accurate current sensing for excellent load line

regulation and accurate OCP

The ISL69125 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.

- Supports ISL99227 60A smart power stage

- Supports DCR sense with integrated temperature

compensation

• Supports external input current sense required for NVDIMM

• Comprehensive fault management enables high reliability

systems

With minimal external components, the ability to store 8

configurations, robust fault management, and highly accurate

regulation capability, implementing a high-performance,

multiphase regulator has never been easier.

- Pulse-by-pulse phase current limiting

- Total output current protection

- Output and input OV/UV protection

- Open voltage sense detect

Applications

• Core and memory for Intel VR13 based designs

- High performance server core and memory rails

- High performance graphics rails

- Black box recording capability for faults

- Configurable Catastrophic Failure Protection (CFP) flag

output

• 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)
