ISL6312CRZ

Product Summary

The ISL6312CRZ is a four-phase PWM control IC. 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. The ISL6312CRZ provides a precision voltage regulation system for advanced microprocessors.
