Digital Dual Output, 4-Phase Configurable, IMVP8 PWM Controller
The ISL69134 is a digital dual output, flexible multiphase
Features
(X+Y ≤ 4) PWM controller designed to be compliant with Intel
IMVP8 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, the
ISL69134 is ideal for controlling the microprocessor core,
memory, and system rails of Intel IMVP8 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
- Dual edge modulation for faster transient response
- Excellent DVID performance
• Flexible phase assignment from 0 to 4 phases per output
• Up to 1MHz operation for high density designs
The ISL69134 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 Intel
• Diode braking for overshoot reduction
• Diode emulation for enhanced light-load efficiency
microprocessors. Device configuration and telemetry
monitoring are accomplished with the intuitive Renesas
PowerNavigator™ GUI. Diode emulation and automatic phase
add/drop features allow the user to extract maximum efficiency
from the converter regardless of load conditions.
• 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 ISL69134 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 IMVP8 based processor
- High performance servers core or memory rail
- High performance graphic rail
- Black box recording capability for faults
- Configurable Catastrophic Failure Protection (CFP) flag
output
• Intuitive configuration with PowerNavigator
- High-end desktop
• SMBus/PMBus v1.3 compatible
- Up to 2MHz bus interface
• Networking, data center, storage, and general purpose
- NVM to store up to eight configurations
• Pb-free (RoHS compliant)
