NCP81111GEVB: 3-phase VR12.5-6 high-speed digital controller with SVID and I2C interface

NCP81111GEVB: 3 Phase VR12.5-6 High Speed Digital Controller with SVID and I2C Interfaces

Overview

The NCP81111GEVB is a high performance digital single output three phase VR12.5?6 compatible buck solution optimized to operate at frequencies up to 5 MHz for Intel CPU applications. The NCP81111 and can also work as a general purpose I2C controlled multiphase voltage regulator. The NCP81111GEVB is designed to support the NCP81163 digital phase doubler IC which expands the capability of the part to 6 phases for high current handling. The controller includes true differential voltage sensing, differential current sensing, digital input voltage feed?forward, DAC feed forward, and adaptive voltage positioning.
