三相降压PWM控制器，带有两个集成MOSFET驱动器和一个外部驱动器信号 Three-Phase Buck PWM Controller with Two Integrated MOSFET Drivers and One External Driver Signal
The ISL6566A three-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 multi phase product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution.
