Digital Dual Output 4-Phase AMD PWM Controller

The ISL69144 is a digital dual output, multiphase PWM

controller designed to be compliant with AMD SVI2

Features

• Advanced linear digital modulation scheme

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 a single output operation as a 4+0

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

assignment along with PMBus and SVI2 interfaces, the

ISL69144 is ideal for controlling the microprocessor core,

memory, and system rails of AMD SVI2 based platforms.

- 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 ISL69144 uses a proprietary digital linear predictive

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. Configuration is accomplished through

the intuitive PowerNavigator™ GUI. Diode emulation and

automatic phase add/drop features allow the user 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 ISL69144 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 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

- Black box recording capability for faults

- Configurable Catastrophic Failure Flag (CFP) output
