ISL6566AIRZ Datasheet PDF - Intersil

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.
