Digital Multiphase Controllers & Smart Power Stage for 10A‑450A Solutions
Intersil's ISL681xx and ISL691xx digital multiphase PWM controllers provide up to seven phases that are assignable in any combination across two outputs. They combine with smart power stages, like the ISL99227, to provide a scalable solution from 10A to 450A. The result is enhanced power optimization and more energy-efficient networking and communications infrastructure equipment.
Intersil's easy-to-use PowerNavigator™ GUI software supports the ISL681xx and ISL691xx products. PowerNavigator connects to development boards communicating across PMBus and AVSBus, allowing engineers to set up and control all parameters, optimize efficiency via precise current thresholds for adding/dropping phases, and adjust the loop tuning.

The ISL69138 is a digital, dual output, flexible, multiphase (X+Y ≤ 7) PWM controller designed to be 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.
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.
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.
With minimal external components, easy configuration, robust fault management, and highly accurate regulation capability, implementing a high-performance, multiphase regulator has never been easier.
