NCP81111 - 3 Phase VR12.5-6 High Speed Digital Controller

General Description

Pin No.

Key Features

  • combine to provide an accurately regulated dynamic voltage system. The control system makes use of digital constant on time modulation and is combined with an analog and digital current sensing system. This system provides the fastest initial response to dynamic load events to reduced system cost. On board user programmable memory is included for configuring the controller’s parameters. User programmable voltage and droop compensation is internally integrated to minimize the total board space us.

NCP81111 3 Phase VR12.5­6 High Speed Digital Controller with SVID and I2C Interfaces for 5 MHz Desktop, Notebook CPU Applications The NCP81111 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 NCP81111 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.
