Product Summary

The ISL6568CRZ is a two-phase buck PWM controller.The ISL6568CRZ 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 multiphase product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution. Outstanding features of the ISL6568CRZ include programmable VID codes compatible with Intel VRM9, VRM10, as well as AMD Hammer microprocessors.
