ISL69147
FN8706
Rev.6.00
Feb 15, 2019
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
