ISL6312IRZ

四相降压PWM控制器，用于Intel VR10 ， VR11 ， AMD和应用集成MOSFET驱动器 Four-Phase Buck PWM Controller with Integrated MOSFET Drivers for Intel VR10,VR11, and AMD Applications

**_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.
