ISL6566, Three-Phase Buck PWM Controller

DATASHEET ISL6566 Three-Phase Buck PWM Controller with Integrated MOSFET Drivers for VRM9, VRM10, and AMD Hammer Applications FN9178 Rev 4.00 Mar 9, 2006 The ISL6566 three-phase PWM control IC provides a precision voltage regulation system for advanced microprocessors.

The integration of power MOSFET drivers into the controller IC marks a departure from the separate PWM controller and driver configuration of previous multiphase product families.

By reducing the number of external parts, this

ISL6566 Features

* of this controller IC include programmable VID codes compatible with Intel VRM9, VRM10, as well as AMD Hammer microprocessors. A unity gain, differential amplifier is provided for remote voltage sensing, compensating for any potential difference between remote and local grounds. The output voltage c
