Description
The ISL69133 is a digital, dual output, flexible, multiphase (X+Y ≤ 4) PWM controller designed to be compliant with Intel VR13/IMVP8 specifications. The digital multiphase controller can be configured to support any desired phase assignments up to a maximum of four phases across the two outputs (X and Y). For example, 3+1, 2+2, or even single output operation as a 4+0 configuration, are supported. With a flexible X+Y ≤ 4-phase assignment, PMBus, and SerialVID (SVID) interfaces, the ISL69133 is ideal for controlling the microprocessor core, memory, and system rails of Intel VR13/IMVP8 platforms. The ISL69133 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 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 ISL69133 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 eight configurations, robust fault management, and highly accurate regulation capability, implementing a high-performance, multiphase regulator has never been easier.
