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
