Digital Dual Output 6+1-Phase VR13 PWM Controller

The ISL69127 is a digital dual output, multiphase PWM

controller designed to be compliant with Intel VR13

specifications. The digital multiphase controller can be

configured to support any desired phase assignments on the

second output channel, up to a maximum of six phases. The

ISL69127 supports the SVID interface along with PMBus v1.3

specifications, making it ideal for controlling the

microprocessor core, memory, and system agent rails of Intel

VR13 platforms.

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 DVID performance

- Dual edge modulation for faster transient response

The ISL69127 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

PowerNavigator™ software. Diode emulation and automatic

phase add/drop features allow the user to extract maximum

efficiency from the converter regardless of load conditions.

• 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

• Highly accurate current sensing for excellent load line

regulation and accurate OCP

The ISL69127 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

• Comprehensive fault management enables high reliability

systems

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.

- 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 via PowerNavigator

Networking, data center, storage, and general purpose

• SMBus/PMBus v1.3 compatible

- Up to 2MHz bus interface
