三相降压PWM控制器集成MOSFET驱动器和轻载效率增强的英特尔VR11.1应用 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 product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution.
