Digital Dual Output, 7-Phase Configurable, IMVP8 PWM Controller
The ISL69137 is a digital dual output, flexible multiphase
Features
(X+Y ≤ 7) 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 seven phases across the two outputs (X and Y).
For example, 6+1, 5+2, 4+2, 3+3, 3+2, or even single output
operation as a 7+0 configuration are supported. The
• 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
ISL69137, with a flexible X+Y ≤ 7 phase assignment, supports
the SVID interface along with the PMBus v1.3 interface,
making it ideal for controlling the microprocessor core,
memory, and system rails per Intel IMVP8 platforms.
- Dual edge modulation for faster transient response
- Excellent DVID performance
• Flexible phase assignment from 0 to 7 phases per output
• Up to 1MHz switching frequency operation for high density
designs
The ISL69137 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
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.
• 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 ISL69137 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
• Supports phase doubler (ISL6617A) for up to 14-phase
operation
With minimal external components, the ability to store up to
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 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
- High-end desktop with overclocking option
• Networking, data center, storage, and general purpose
• Intuitive configuration with PowerNavigator
