Digital Dual Output, 7-Phase Configurable, VR13/VR13.HC/IMVP8 PWM Controller

Product Status: Mass Production


The ISL69158 is a digital dual output, flexible multiphase (X+Y ≤ 7) PWM controller designed to be compliant with Intel VR13/VR13.HC and 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 ISL69158, with a flexible X+Y ≤ 7 phase assignment, supports the SVID interface along with PMBus 1.3 specifications, making it ideal for controlling the microprocessor core, memory, and system rails of Intel VR13/VR13.HC or IMVP8 platforms.

The ISL69158 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. The device is configured and monitored with the intuitive Renesas 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 ISL69158 supports a comprehensive fault management system to enable the design of highly reliable systems. From a multitiered 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.
