Digital Dual Output, 7-Phase Configurable, IMVP8 PWM Controller
Jump to Page Section:
Overview
Description
The ISL69137 is a digital dual output, flexible multiphase (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 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. 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. 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. 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.
