The ISL69144 is a digital dual output, multiphase PWM controller designed to be compliant with AMD SVI2 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 a single output operation as a 4+0 configuration are supported. With a flexible X+Y ≤ 4-phase assignment along with PMBus and SVI2 interfaces, the ISL69144 is ideal for controlling the microprocessor core, memory, and system rails of AMD SVI2 based platforms. The ISL69144 uses a proprietary digital linear predictive 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 AMD microprocessors. The configuration is accomplished through the intuitive 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 ISL69144 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.
