ISL6333B, ISL6333, Three-Phase Buck PWM Controller
ISL6333, ISL6333A, ISL6333B, ISL6333C ® Data Sheet March 19, 2009 FN6520.1 Three-Phase Buck PWM Controller with Integrated MOSFET Drivers and Light Load Efficiency Enhancements for Intel VR11.1 Applications 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
ISL6333B 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 from the VR11 DAC table. A circuit is pr
