The ISL6322G two-phase PWM control IC provides a precision voltage regulation system for advanced microprocessors and memory. 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.
