The ISL69147 is a digital dual output multiphase (X + Y = 7) PWM controller that is compliant with AMD SVI2 specifications. The digital multiphase controller can be configured to support any phase assignments across the two outputs (X and Y). The ISL69147 supports the PMBus V1. 3 and SVI2 interfaces, so the device is ideal for controlling the microprocessor core, memory, and system rails for AMD SVI2 based platforms. When the ISL69147 is configured to use the SVI2 interface, Rail 1 can support a maximum of six phases and Rail 2 must have one phase assigned. The ISL69147 uses a 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 AMD microprocessors. You can use the intuitive Renesas PowerNavigator™ software to configure the device. Diode emulation and automatic phase add/drop features allow you to extract maximum efficiency from the converter regardless of load conditions. The ISL69147 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 configurable power-good and catastrophic fault protection flags, almost 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.
