Overview

The ISL69125IRAZ-T7A is a digital dual output, flexible multiphase (X+Y ≤ 4) PWM controller designed to be compliant with Intel VR13 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, it is ideal for controlling the microprocessor core, memory, and system rails of Intel VR13 platforms.The ISL69125IRAZ-T7A 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 telemetry 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 ISL69125IRAZ-T7A 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.With minimal external components, the ability to store 8 configurations, robust fault management, and highly accurate regulation capability, implementing a high-performance, multiphase regulator has never been easier.
