ISL6333A 3-Phase Buck PWM Controller

DATASHEET ISL6333, ISL6333A, ISL6333B, ISL6333C Three-Phase Buck PWM Controller with Integrated MOSFET Drivers and Light Load Efficiency Enhancements for Intel VR11.1 Applications FN6520 Rev 3.00 Oct 8, 2010 The ISL6333 three-phase PWM family of control ICs provide 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 multi-phase .

ISL6333A Features

* that make these controllers compatible include an IMON pin for output current monitoring, and a Power State Indicator (PSI#) pin for phase dropping and higher efficiency during light load states. An 8-bit VID input is used to select the desired output voltage
