Digital, Dual Output, 7-Phase Configurable, VR13/IMVP8 PWM Controller
The ISL69138 is a digital, dual output, flexible,
multiphase (X+Y ≤ 7) PWM controller designed to be
Features
• Advanced linear digital modulation scheme
compliant with Intel VR13 and IMVP8 specifications.
The 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. The ISL69138, with a flexible X+Y ≤
7 phase assignment, supports the SVID interface along
with PMBus 1.3, making it ideal for controlling the
microprocessor core, memory, and system rails for Intel
VR13 or IMVP8 platforms.
• Zero latency synthetic current control for
excellent HF current balance
• Auto phase add/drop with a boot refresh function
for excellent load vs efficiency profile
• Dual edge modulation for faster transient
response
• Excellent Dynamic Voltage Identification
(DVID) performance
• Flexible phase assignment from 0 to 7 phases per
output
The ISL69138 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
using the intuitive PowerNavigator™ software. Diode
emulation and automatic phase add/drop features allow
the user to extract maximum efficiency from the
converter regardless of load conditions.
• Up to 1MHz switching frequency operation for high
density designs
• 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 ISL69138 supports a comprehensive fault
management system to enable the design of highly
reliable systems. From a multi-tiered overcurrent
protection scheme to the configurable power-good and
catastrophic fault protection flags, almost 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, easy configuration,
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
Applications
• Core, memory, and system rails for Intel VR13 and
IMVP8 based processors
• Output and input OV/UV protection
• Open voltage sense detect
• High performance servers core or memory rail
• High performance graphics rail
• Black box recording capability for faults
• Configurable Catastrophic Failure Protection
(CFP) flag output
• High-end desktop with over-clocking option
• Networking, data center, storage, and general
purpose
• Intuitive configuration using PowerNavigator
• SMBus/PMBus V1.3 compatible
