Digital Dual Output 7-Phase AMD PWM Controller

The ISL69147 is a digital dual output multiphase (X + Y = 7)

PWM controller that is compliant with AMD SVI2

Features

• Advanced linear digital modulation scheme

specifications. The digital multiphase controller can be

configured to support any phase assignments across the two

outputs (X and Y). The ISL69147 supports the PMBus V1.3 and

SVI2 interfaces, so the device is ideal for controlling the

microprocessor core, memory, and system rails for AMD SVI2

based platforms. When the ISL69147 is configured to use the

SVI2 interface, Rail 1 can support a maximum of six phases

and Rail 2 must have one phase assigned.

- 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

• Up to 1MHz operation for high density designs

• Diode braking for overshoot reduction

The ISL69147 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

AMD microprocessors. You can use the intuitive Renesas

PowerNavigator™ software to configure the device. Diode

emulation and automatic phase add/drop features allow you

to extract maximum efficiency from the converter regardless

of load conditions.

• 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

- Supports ISL99227 60A smart power stages

The ISL69147 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 configurable power-good and catastrophic fault

protection flags, almost any need is accommodated.

- Supports DCR sense with integrated temperature

compensation

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

operation

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.

• 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 and graphics for AMD SVI2 based processors

- High performance servers core rail

- Black box recording capability for faults

- Configurable catastrophic failure flag output (CFP)

- High performance graphic rail

• Intuitive configuration using PowerNavigator

- High-end desktop with overclocking option

• Networking, data center, storage, and general purpose

• SMBus/PMBus V1.3 compatible

- Up to 2MHz bus interface
