●_Four-Phase Buck PWM Controller with _

●_Integrated MOSFET Drivers for Intel VR10, _

●_VR11, and AMD Applications_

●The ISL6312 four-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 integration is optimized for a cost and space saving power management solution.
